Converts on your device — your PDF is never uploadedJPG & PNG to PDF — Lossless, Assembled in Your Browser
Combine JPG, PNG and other images into a single PDF — drag the pages into order, pick A4, Letter or fit-to-image, and set margins and orientation. Two things set this apart: your files are never uploaded, and JPEGs are embedded byte-for-byte with no re-compression, so the images inside the PDF are pixel-identical to your originals. Free, no sign-up, no watermark, no limits.
How This Compares
| This converter | Typical online converter | |
|---|---|---|
| Where it runs | Your browser | Their servers |
| Your images are uploaded | Never | Yes, every time |
| JPEG quality | Untouched (byte-for-byte) | Often re-encoded, sometimes at 75% |
| File retention | Nothing to retain | “Deleted after 1–2 hours” |
| Works offline | Yes, once loaded | No |
| Watermark / sign-up | Neither | Common on free tiers |
How to Convert Images to PDF
- Add your images — drag and drop, click to browse, or paste. Add as many as you like, in any mix of formats.
- Put them in order — drag a thumbnail to move it, or use the arrows on each card. Page numbers update as you go.
- Choose the page setup — fit-to-image for a borderless album, or A4/Letter/Legal/A3/A5 with a margin for a proper document. Auto orientation rotates each page to match its picture.
- Create and download — one PDF, ready to print, email, sign or upload.
Choosing a Page Size
| Setting | What you get | Best for |
|---|---|---|
| Fit to image | Each page exactly the shape of its picture | Photo albums, screenshots, comics, borderless output |
| A4 | 210 × 297 mm (8.27 × 11.69 in) | Documents everywhere outside North America |
| US Letter | 8.5 × 11 in (216 × 279 mm) | North American printing and forms |
| Legal | 8.5 × 14 in | Contracts and long-format legal paperwork |
| A3 / A5 | Double / half A4 | Posters and plans / booklets and handouts |
A4 versus Letter is the most common confusion, and the difference is small but real: A4 is taller and narrower, Letter is shorter and wider. Neither prints correctly on the other without scaling or clipping, so pick the one your recipient actually prints on — Letter for the US and Canada, A4 almost everywhere else.
Orientation, Margins and Placement
Auto orientation looks at each image and rotates that page to match — landscape photos get landscape pages, portrait shots get portrait pages. Force one or the other if you need every page identical, for example when the PDF will be printed and bound.
Fit inside shrinks the image until all of it is visible, which can leave blank strips where the image and page shapes disagree. Fill page enlarges it until the page is fully covered and crops the overflow. Use fit inside for anything where losing an edge would matter — scans, receipts, documents — and fill page for photographs where borders would look untidy.
Margins only apply to standard page sizes. A small margin (about 6 mm) suits most documents; larger margins help when a page will be hole-punched or bound.
Page Order Follows the Thumbnails, Not the Filenames
This trips people up constantly. Phone cameras name files things like IMG_20260726_184233.jpg, scanners often number pages backwards, and a file manager sorts page10 before page2. Whatever the names, the PDF is built in the order the thumbnails appear — so drag them once and the document is right.
Three Ways to Control File Size
| Mode | What it does | Use when |
|---|---|---|
| Lossless | JPEGs embedded byte-for-byte; nothing re-encoded | Quality matters most — printing, archiving, artwork |
| Set quality | Re-encodes every image at a JPEG quality you choose | You want a smaller file and know roughly what you need |
| Target size | Tries several quality levels and keeps the best one that fits your limit | An upload cap must be met — “under 200 KB”, “max 2 MB” |
Lossless means the PDF is roughly the combined size of your images plus a small overhead — in testing, a 57 KB JPEG produced a 62 KB single-page PDF. That is the honest cost of keeping every pixel.
Target size is the one that saves arguments with upload forms. Enter the limit — 200 KB, 1 MB, whatever the portal demands — and the tool builds the document several times at different quality levels, keeping the highest quality version that still fits. It reports the size achieved and the quality used, and if your target is simply unreachable at those page settings it says so plainly rather than handing you an oversized file.
Limits worth knowing: Gmail attaches up to 25 MB and Outlook.com 20 MB, while government, university and job-application portals commonly cap uploads at 2 MB, 1 MB or even 200 KB per file. If a target cannot be met, the fastest fix is to reduce the source images first with the Image Resizer — a 12 megapixel phone photo carries far more detail than any printed page can show.
What People Use This For
- Turning phone photos of documents into one file — the everyday substitute for a scanner.
- Job and visa applications — portals that demand a single PDF of certificates, IDs and transcripts.
- Expense claims — a dozen receipt photos become one attachment instead of twelve.
- Portfolios and proofs — sending a set of images as one document that opens identically for everyone.
- Signed paperwork — photographing signed pages and combining them for the other party.
- Archiving — keeping a scanned set together in a format that will still open in decades.
Supported Formats, and What Happens to Each
| Input | How it is stored in the PDF | Quality |
|---|---|---|
| JPG / JPEG | Original JPEG stream embedded directly | Identical to source |
| PNG | Embedded with lossless compression | Identical to source |
| WebP, GIF, BMP, HEIC | Decoded, then stored losslessly | No loss from the conversion itself |
PDF only understands a couple of image encodings natively, which is why JPG and PNG pass straight through while other formats are decoded first. Nothing is thrown away in either path unless you deliberately switch on re-compression.
Is It Safe and Private?
Yes, and you can prove it rather than take it on trust: load this page, disconnect from the internet, and build a PDF. It still works, because the document is assembled by your own browser. No upload, no account, no watermark, and no copy of your photos on anyone else’s disk — which matters when you are photographing a passport, a bank statement or a signed contract.
Troubleshooting
The pages came out in the wrong order
Order follows the thumbnails, not the filenames. Drag them into place before creating the PDF, or use the arrow buttons on each card.
My photo is cropped
You have Fill page selected, which crops to cover the page. Switch to Fit inside to keep the whole image.
The PDF is too big to email
Switch on re-compression and set the quality to about 75–80. If it is still too large, resize the source photos first with the Image Resizer — a 12 megapixel photo is far more detail than any printed page needs.
My HEIC photos will not load
HEIC needs an extra decoder, which loads on demand the first time you add one. Give it a moment on a slow connection, then try again.
Frequently Asked Questions
How do I convert JPG to PDF?
Drop your images onto the upload area - add as many as you like. Drag the thumbnails into the order you want, choose a page size, margin and orientation, then press Create PDF and download. Everything happens in your browser, so nothing is uploaded.
Can I combine multiple images into one PDF?
Yes, and that is the normal way to use it. Every image becomes one page of a single PDF, in the order you arrange the thumbnails. There is no limit on how many you add.
Does converting to PDF reduce image quality?
Not here. JPEG files are embedded into the PDF byte-for-byte with no decoding and no re-compression, so the image inside the PDF is pixel-identical to your original. PNG images are embedded with lossless compression. This is worth checking elsewhere: at least one well-known converter states in its own help pages that it re-encodes images with JPEG compression at 75% quality by default.
Is my image uploaded to a server?
No. The PDF is assembled inside your browser. Your images never leave your device. Several major converters describe cloud processing plainly - PDF24 states that generation happens on their servers, and Smallpdf and FreeConvert describe deleting uploaded files after an hour or a few hours.
Can I reorder the pages?
Yes. Drag any thumbnail to a new position, or use the arrow buttons on each card. The PDF follows the order shown on screen, not the filenames - which matters because phones and cameras rarely name files in the order you want them.
Should I choose Fit to image, A4 or Letter?
Fit to image keeps each page exactly the shape of its picture with no borders, which suits photo albums and screenshots. A4 or US Letter gives every page a standard document size, which is what you want for printing or submitting something official. A4 is taller and narrower (8.27 x 11.69 in); Letter is shorter and wider (8.5 x 11 in).
What is the difference between Fit inside and Fill page?
Fit inside scales the image down until the whole thing is visible, which can leave blank strips at the sides. Fill page scales it up until the page is completely covered, cropping whatever overflows. Use Fit inside for documents and scans where nothing may be lost, and Fill page for photos where borders would look untidy.
Which image formats can I use?
JPG, PNG, WebP, GIF, BMP and HEIC from iPhone. JPG and PNG are embedded losslessly; the others are converted to a lossless PNG internally first, because the PDF format itself cannot store them directly.
How do I make the PDF smaller?
Switch to Set quality and lower the slider, or use Target size and simply name the limit you need.
Can I make a PDF under 200 KB?
Yes — choose Target size, enter 200 KB, and the tool finds the best quality that fits under it, reporting exactly what it achieved.
Does it keep PNG transparency?
PDF pages have a white background, so transparent areas appear white in the finished document. The transparency data is preserved in the embedded image, but a PDF page is not transparent the way a PNG is.
Is there a limit on the number of images?
No artificial limit. Because everything runs on your device, memory is the only real constraint - dozens of high-resolution photos are comfortable on a desktop.
Will the PDF open everywhere?
Yes. It is a standard PDF built to the same specification Acrobat uses, so it opens in every PDF reader, browser, phone and printer, and can be signed or annotated like any other.
