About the PNG to PDF
Turn a PNG, or a whole stack of them, into one clean PDF without leaving the browser. Add JPGs to the same file if you've got them, order the pages with the arrows, download. No account, no upload, no watermark, no cap on how many images you combine.
The reason to use this one over the dozens of free PNG-to-PDF sites comes down to what PNG is actually for. You save something as PNG when the pixels have to stay sharp: a screenshot full of small text, a scanned receipt, an ID, a signature, a diagram with thin lines. Those files are private, and they're detailed, and the typical free converter abuses both facts. It uploads your image to a server somewhere, runs the job there, and lets you download the result, usually with a line about deleting your file within the hour. For a public flyer that's a fine trade. For a scan of your passport or a receipt with a card number on it, you've handed a copy of a private document to a company you know nothing about and taken their word on the cleanup. This tool doesn't make you take anybody's word. Your images never leave the device. They're read straight off your disk, the PDF is put together right there in the page, and it downloads back to you. Switch off your wifi once the page has loaded and it still builds the file, which is about as clear as proof gets that nothing is being sent anywhere.
How to use
- Drag your PNGs onto the drop zone, or click it to browse and pick them. You can select a batch at once, and you can mix JPGs into the same batch.
- Put the pages in order. Each image sits in a numbered list, and the up and down arrows next to it move it. Top of the list becomes page one.
- Choose the page sizing. Tick "Fit each image to an A4 page" for a uniform printable document, or leave it off to keep each page the size of its own image.
- Click Create PDF. It's built on your device and downloads right away, saved as images.pdf.
Remove any image you added by accident with the X beside it, or hit Clear to start over. Nothing to install, nothing to sign up for.
Keeping screenshots sharp
When this tool builds the PDF, your image goes in losslessly. No quality gets thrown away to make the file smaller, so an image that was sharp going in is exactly as sharp coming out, with nothing softened along the way. Most converter pages never mention this, and for PNG it's the thing that matters most.
PNG is lossless by design, which is why screenshots, logos, diagrams and anything full of text end up in it. Crisp edges stay crisp instead of smearing the way a lossy format does. A converter that re-encodes your PNG to trim the file size can quietly wreck that, and you usually don't catch it until you zoom in on the finished PDF and the small print looks chewed. This tool skips that re-encode step, so the original pixels go straight into the PDF unchanged.
The catch is file size. Since none of the quality gets thrown away, the PDF lands about as heavy as your images, sometimes heavier. A dozen big phone screenshots make a big PDF. If you need it lighter, shrink the source images before you combine them. There's no quality slider here to claw the size back afterward, and leaving it out is deliberate: a slider that silently degrades your PNG is the exact thing this tool refuses to do.
Combining a stack in the right order
Most people aren't here to convert a single PNG. They've got a pile of separate images that really should be one document. Four shots of a signed lease. A folder of receipts for an expense claim. A run of screenshots documenting a bug. Add them all and each one becomes a page, in the order you set. If your files are mostly photos rather than screenshots, the JPG to PDF version is the same engine aimed at that job, and there's a plain Image to PDF door in if that name fits better.
Order is the part people get wrong, so the tool keeps it visible. The numbered list is the page order, top to bottom. Say you shot a three-page contract but grabbed page two last because you flipped back to check something. Drop all three in, then arrow page two into the middle where it belongs. Fixing it here, before you build, is far less painful than trying to reshuffle pages inside a finished PDF later.
There's no built-in limit on how many you add. The only real ceiling is your browser's memory, which handles normal scans and screenshots easily, though a huge batch of very high-resolution photos will lean on it harder. PNG and JPG can sit in the same document freely, so a folder that happens to hold both is no problem. If instead you already have separate PDFs you want joined end to end, that's a different job and Merge PDF is the tool for it.
A4 or the image's own size
One setting changes how the finished PDF looks and prints, so it's worth a second of thought. Ticking "Fit each image to an A4 page" drops every image, centered, onto a standard A4 sheet (210 by 297 mm), scaled to fit. Every page comes out the same size and shape no matter how mismatched the images were. That's what you want when the PDF has to print cleanly or sit in a folder next to other paperwork. A tall receipt and a wide screenshot both land on an identically sized page, and the whole thing reads as one tidy document.
Leave it unticked and each page is made the exact size of the image on it, edge to edge, no border at all. This is the one for a photo set, a portfolio, or a sequence of screenshots where a white margin around each would just be dead space. It keeps every image at its native proportions.
If you can't decide, go A4. Almost any PDF gets printed by somebody eventually, and a standard page size is what printers expect.
Frequently asked questions
Why does my PDF look blurry in the viewer but sharp when I zoom in?
Some PDF viewers downscale images to fit the screen and only render full detail once you zoom. The pixels in the file are intact, because your PNG is embedded losslessly. If it looks soft at full-page zoom but crisp at 100 percent, that's the viewer doing the softening, not the conversion.
Do camera photos come out the right way round?
They do, and it matters more than it sounds. A camera stores a shot in sensor order and puts the rotation in a tag next to it, so a portrait photo is really a landscape image with a note attached. That note gets read here and the picture is turned as it is placed, which is why a batch of PNG screenshots mixed with JPGs off a phone comes out with every page the shape it should be. A PNG hardly ever carries that tag, so screenshots and exports were never the ones at risk anyway.
Can I add a PNG with a transparent background?
Yes, the transparency is kept. On a page sized to the image, the see-through areas show whatever the viewer puts behind the page, usually white. Fit it to A4 and those areas simply show the white sheet through them. If you need a specific color behind the image, flatten the PNG onto that color in an editor before adding it.
What can I add besides PNG?
JPG, mixed into the same batch in any order. Those two are the formats that can be placed into a PDF this way. Drop in something else, a GIF, a WebP, a HEIC straight off an iPhone, and it gets skipped with a note telling you so. Convert those to PNG or JPG first, then add them.
If I add more images later, does it scramble the order I already set?
No, the order you set holds. New files drop to the bottom of the list in the order you pick them, so everything you already arranged keeps its spot. Add a page you forgot halfway through and you only have to arrow that one into place, rather than rebuild the whole sequence.
Does it work on a phone?
Yes, it runs in a mobile browser exactly like it does on a desktop. That's handy when you've photographed a few pages and a portal will only take one PDF. Add the photos, order them with the arrows, build, and upload the single file, all without leaving the phone.
