This free JPG to PDF converter turns your photos into one ordered document directly in the browser. Combine up to 30 images, keep every phone photo upright, choose the paper, margins and image quality, preview the finished PDF and download it — without uploading anything and without signing up.
People search for this task with many phrasings — convert JPG to PDF, change JPG to PDF, JPG to PDF online — but the underlying job is stable: one or more JPEG files should become a clean, shareable document. What separates a good result from a frustrating one is not the file extension. It is whether the pages come out in the right order, the right way up, at a readable size and at a file weight the destination will accept.
This page keeps those decisions explicit. It also shows the actual generated PDF before you download it, and it warns you in advance when a layout choice would crop a photo edge.
How to convert JPG to PDF on this page
- Choose your JPG files. Use the picker or drop the files into the upload area. Add up to 30 images; each one becomes one page. PNG, WebP and GIF files are also accepted if a batch is mixed.
- Put the pages in order. The numbered cards are the exact sequence of the finished document. Drag a card, or use the arrow buttons on a touch screen.
- Fix any sideways page. Rotate an individual image left or right in 90-degree steps. Only that page changes.
- Choose the page layout. A4, US Letter, US Legal or Match each image, with automatic, portrait or landscape orientation and a margin from None to Wide.
- Choose the image fit. Fit whole image keeps every edge visible. Fill the page removes white borders but can crop.
- Choose the page encoding. Balanced PDF is the practical default; High-quality PDF keeps more detail; Lossless pages avoid new JPEG compression entirely.
- Name the document and optionally add page numbers, then select Create PDF.
- Inspect the result. Page through the preview, read the crop report and file size, then download.
Changing any source or setting clears the previous result, so the preview always matches the controls you currently see. The original JPG files on your device are never modified — the converter reads them and writes a new file.
Combine and merge JPG files into one PDF
Searches like JPG to PDF and merge, JPG to PDF combine and combine JPG to PDF describe the most common version of this task: several separate photos should arrive as a single document — receipts for an expense report, pages of a signed form, artwork for a client.
On this page, merging is the default behavior rather than a separate mode. Every image you add becomes one page in one PDF, and the order shown before conversion is the order in the file. That matters more than it seems: phones and cameras name files in ways that do not always sort the way a reader expects, so check the first card really is the page that should open first.
Two details make the merge predictable here:
- Per-image rotation. A wide chart can stay landscape while the surrounding pages stay portrait. Rotation belongs to the page, not the document.
- Automatic orientation per page. A single PDF can mix portrait and landscape pages while keeping one paper standard — verified in the worked example below.
What this tool does not do is place several JPGs onto the same page or stitch them into a collage. "Merge" here means one ordered document, one image per page.
Keep phone photos upright without extra work
JPG files from phones and cameras carry an orientation flag in their EXIF data. The sensor may have recorded the photo sideways; the flag tells viewers to rotate it for display. Converters that ignore the flag produce PDFs with sideways pages — a common complaint with phone photos of documents.
This tool reads the image with the orientation flag applied, using the browser's createImageBitmap() decoding, so the page is built from the photo as you see it. If a photo still ends up the wrong way round — for example a scan saved with a wrong flag — use that page's rotate buttons instead of reconverting the whole batch.
One honest side effect: because every page image is freshly prepared, the original EXIF block — camera model, GPS coordinates, timestamps — is not copied into the PDF. For sharing documents with strangers, that is usually a privacy benefit. If you need the metadata preserved, use a tool that embeds the original file unchanged.
Choose the page size, orientation and margins
The page setting controls the PDF page itself, independently of how many pixels each photo has.
| Page option | Choose it when | Result on this page |
|---|---|---|
| A4 | The recipient expects standard international office paper | 8.27 × 11.69 in pages in the selected orientation |
| US Letter | The recipient expects North American paper | 8.5 × 11 in pages |
| US Legal | A longer North American page is required | 8.5 × 14 in pages |
| Match each image | The PDF should follow each photo's own shape | Page size is calculated from the image at the selected scale |
Auto per page orientation follows each image's shape, so mixed batches need no manual sorting into portrait and landscape groups. Fix the orientation only when a receiving system insists every page face the same way.
Margins add white space between the photo and the page edge: None, Narrow (0.25 in), Normal (0.5 in) or Wide (0.75 in). A margin helps when the PDF will be printed and punched for a binder; None suits photos meant to fill the page. A printer may still enforce its own non-printable border, so a zero-margin PDF does not guarantee borderless printing.
With Fit whole image, the complete photo is always visible and empty space may remain on two sides. With Fill the page, the photo covers the page and differing aspect ratios cause cropping. The form estimates how many pages would crop before you convert, and the result report names the cropped pages — when the warning appears, rotate the source or switch to Fit whole image rather than discovering the loss after sending the file.
JPG quality and the final PDF file size
A PDF built from JPGs is not a zip of the original files. Each page image is re-encoded, and the mode you choose sets the trade-off between fidelity and weight:
- Balanced PDF — JPEG at 82%. The default for photos of documents, receipts and forms where a moderate file size matters.
- High-quality PDF — JPEG at 94%. A larger file that keeps more fine texture; it cannot restore detail the source never had.
- Lossless pages — PNG encoding. No new JPEG compression at all, but detailed photographs can make the PDF several times larger.
This choice is the direct connection between the guide and the form: if the Balanced result visibly softens small text on a receipt, recreate the PDF with High-quality and compare the reported file size before deciding. The size shown in the result panel is the actual generated file, not an estimate.
Note that the direction of change is not guaranteed. A small, heavily compressed JPG placed on a large page can produce a bigger PDF than the source; a set of huge camera files will usually shrink. Judge by the reported output, not by assumption. When the sources themselves are far larger than needed, resizing or compressing the images first reduces the PDF more predictably than lowering quality afterward.
Check the PDF before you download it
The result area shows the real generated document, not a mockup. Before downloading:
- Page through the preview and confirm the order and orientation of every page.
- Look at all four edges of any page marked as cropped.
- Confirm the page count equals the number of source images.
- Compare the PDF size with the combined source size and with any limit at the destination.
- Check that page numbers, if enabled, do not fight with the content.
The built-in preview varies between browsers and devices. For an important submission, open the downloaded file itself once before sending it.
Worked example: three mixed photos to one A4 PDF
A typical batch: two phone photos of a signed contract (one held landscape, one portrait at 4000 × 3000 and 3000 × 4000 pixels) plus a square 2048 × 2048 scan. Choose A4, Auto per page, Narrow margin and Fit whole image.
Computed with the tool's own layout functions, the result is:
| Source | PDF page | Image scale | Cropped |
|---|---|---|---|
| 4000 × 3000 (landscape) | A4 landscape, 11.69 × 8.27 in | 18.6% | No |
| 3000 × 4000 (portrait) | A4 portrait, 8.27 × 11.69 in | 18.6% | No |
| 2048 × 2048 (square scan) | A4 portrait, 8.27 × 11.69 in | 27.3% | No |
One document, three pages, two orientations, nothing cropped — and no manual page-by-page setup. The same assembly path was run end to end during development: the generated file reloads as a valid two-page PDF with the chosen document title in its metadata.
The page dimensions and scales above are verified outputs of the tool's layout calculations. The final file size depends on photo content and the chosen encoding; read it from the result panel.
What this JPG to PDF converter does not do
Being clear about limits saves you a wasted upload elsewhere. This page does not:
- add images to an existing PDF, merge existing PDF files or edit PDF text;
- run OCR — words visible in a scan stay pixels, not searchable text;
- target an exact output size such as 200 KB;
- import files from Google Drive or Dropbox;
- place several photos on one page or create collages;
- preserve original EXIF or GPS metadata in the new pages;
- guarantee acceptance by a specific third-party form.
For mixed PNG or WebP batches that need the same layout controls, the Image to PDF converter presents the identical workflow framed for general images. iPhone photos in HEIC format can be converted with the HEIC to JPG tool first, then assembled here.
Established alternatives approach the task differently: iLovePDF JPG to PDF and Smallpdf JPG to PDF run conversions on their servers inside larger PDF suites with optional cloud imports, while Sejda JPG to PDF offers similar layout controls plus an offline desktop app. The practical distinction of this page is the combination in one place: local in-browser processing, EXIF-aware upright pages, per-page auto orientation, explicit fit-versus-fill behavior with advance crop warnings, three quality modes and a previewable result report — with no account, queue or upload.
Troubleshooting common JPG to PDF problems
A photo appears sideways in the PDF
Use the rotate buttons on that page's card and recreate the PDF. Auto orientation chooses the paper direction from the image shape; it cannot know whether the text inside the pixels reads upright.
The pages are in the wrong order
Rearrange the cards with drag-and-drop or the arrow buttons, then create the PDF again. Any change to order or settings clears the previous result on purpose.
Text or signatures are cut off
You are using Fill the page. Switch to Fit whole image, or rotate the source so its shape matches the paper better. Recreate and confirm the report shows no cropped pages.
The PDF is too large for the destination
Choose Balanced PDF instead of High-quality or Lossless, or reduce oversized sources with the image compressor first. This tool reports the actual size but does not target an exact KB or MB value.
A file is rejected
Confirm each file is a JPG, PNG, WebP or GIF image no larger than 40 MB, with no side longer than 12,000 pixels and no more than 60 megapixels, and that the batch stays within 30 images and 200 MB in total. Renaming an unsupported file to .jpg does not make it a valid image.
The browser struggles with a large batch
Decoded photos and the finished PDF are held in browser memory. Remove unneeded pages, split the batch or close memory-heavy tabs. Very large archival jobs suit a desktop workflow better.
JPG to PDF FAQ
Is this JPG to PDF converter free?
Yes. This page converts and downloads the PDF without a sign-up, payment or watermark step. The conversion runs locally in your browser rather than through a base97 upload service.
Can I combine multiple JPGs into one PDF?
Yes. Add up to 30 images, arrange them in the required order and create one PDF. Each image becomes exactly one page.
Does converting JPG to PDF reduce image quality?
Each page is freshly encoded. Balanced PDF uses JPEG at 82% and High-quality PDF uses JPEG at 94%. Choose Lossless pages to avoid any new JPEG compression, at the cost of a larger file.
Will my phone photos stay upright in the PDF?
Yes. The tool reads the orientation stored in JPG files and applies it when building each page. You can also rotate any page manually in 90-degree steps before converting.
Are my photos uploaded, and is EXIF data kept?
Photos are decoded and assembled locally in the browser; they are not sent to a base97 server. The new page images do not carry over original EXIF, GPS or image-file metadata.
Research and editorial notes: Tool behavior was checked against the base97 implementation on October 3, 2026, including an end-to-end assembly of a mixed-orientation PDF with the shipped layout code. Image decoding behavior was reviewed against MDN documentation for createImageBitmap() and toBlob(); PDF assembly uses pdf-lib. Competitor descriptions reflect their official product pages as observed on the research date and explain scope rather than claim universal superiority.
