Shrink a heavy PNG photograph into a light JPG that any form, phone or print shop accepts.
Swap: JPG to PNGPNG is built for crisp graphics. When the picture is a photograph, its size becomes the problem — and JPG is the format that solves it.
A 12 megapixel photo saved as PNG can easily pass 20 MB, because every pixel is stored in full. The same frame as a JPG at quality 82 usually lands under 2 MB, and nobody can spot the difference on a screen. That is the difference between a mail that sends and a mail that bounces off an attachment limit.
Photo labs, print shops, passport-photo forms, ID uploads, marketplaces and older desktop software all list JPG as the safe type. Where a PNG is silently refused or rendered with a black box where the transparency was, a JPG behaves exactly as expected.
Screenshots pasted into a chat, photos attached to a form, images pushed to a CMS: a file a few times lighter arrives sooner and costs less data. For a single photo this is the simplest saving available, without opening an editor.
Four things change, and one of them is permanent — worth knowing before you click.
JPG has no transparency at all, so every see-through pixel has to be painted over. White is preselected here, which is what most forms and print shops expect; black is the other option in the Background field. Either way the result is opaque, so keep the PNG when the picture will sit on a coloured page.
Quality 82 is the default and a good trade for photos; 80–90 keeps detail while most of the weight disappears, below 60 gradients start to band. The PNG stays lossless forever, this JPG does not — so keep the original and export again rather than re-saving the JPG each time you edit.
A screenshot of text, a chart or a flat logo is mostly hard edges, which is where JPG is weakest: it can come out the same size, or bigger, with visible fuzz around the letters. If the file is small already and the edges are sharp, stay on PNG or move to WebP instead.
A PNG has no EXIF rotation tag, but photos that started life elsewhere and were resaved as PNG still carry one; it is applied on the way through, so the JPG comes out the right way up. Camera details, colour profiles and text chunks are not carried into the JPG, and an animated PNG arrives as its first frame only.
Three steps, and the defaults are already sensible.
Drag it onto the box, click to browse, or paste it with Ctrl+V (Cmd+V on a Mac). One file per run, up to 25 MB — a bigger PNG is easier to shrink first than to upload.
Leave quality at 82 for photos, raise it towards 90 for a picture that will be printed. Type a width only when the JPG is going somewhere smaller than the original; the height follows and the image is never enlarged.
The preview shows the result and the size saving next to the original, so you can lower the quality once more if the file is still too heavy. One click saves the JPG with the original name.
The wrong file type costs more than the wrong quality setting.
A photo with soft gradients: JPG, no question. A logo, an icon, a screenshot of code or a chart: those belong in PNG, or in WebP if you want a smaller web copy that keeps transparency. Turning line art into a JPG makes it look worse and often does not even save bytes.
White is the safe default for a form or a print. If the picture is a cut-out product shot that will end up on a dark page, convert it onto black instead, or keep it as a PNG — a white rectangle around the subject is very visible on a coloured layout.
Going the other way is one click on the JPG to PNG converter, but it cannot undo the compression or recreate the transparency. If the original PNG is still around, keep it: that file is your master, and every JPG should be exported from it rather than from another JPG.
Yes. No account, no trial, no credit card and no watermark on the JPG you download, and the number of conversions is not capped. A short rate limit stops one visitor from occupying the server for everyone else.
They are filled with white, because JPG has no way to store transparency. White is preselected for exactly that reason: it matches paper, forms and most print services. Black is available in the Background field if the picture will sit on a dark layout, and keeping the PNG is the right answer when neither works.
A little, once. JPG is lossy, so at lower quality settings fine detail and smooth gradients suffer first. At the default of 82 the difference is very hard to see on screen, and quality 90 is close to invisible even when printed. The PNG itself stays untouched on your device.
Up to 25 MB per file, with the image itself at most 50 megapixels. A PNG that large is usually a photo, and a width around 2000 px is enough for anything on screen — set it here and the conversion starts from far fewer pixels.
Files are processed on our server and not stored. The PNG is converted as it arrives and only the finished JPG is sent back to your browser.
