JPG to PNG

JPG is the right format for storing and sharing photographs, so moving to PNG is rarely about making a picture look better. It is about what you plan to do next. Convert when a website or app will only accept PNG files, when you want a lossless working copy that holds up through repeated edits, or when you need a base image that can carry a transparent background once you open it in an editor.

For sending or posting a photo as it stands, the original JPG is usually the smaller and more sensible choice. The tool leaves that decision with you and does the conversion the moment you actually need it, without pushing you toward a format that does not suit the job.

JPG and PNG solve different problems, so the better format depends on the image. JPG uses lossy compression that is tuned for photographs. It drops fine detail the eye tends to overlook, which keeps photo files small and quick to share. The cost is that a little quality is lost every time a JPG is saved again.

PNG uses lossless compression and keeps every pixel in full. It works best on screenshots, logos, icons, charts and anything with sharp edges, flat colour or text, where JPEG would leave a soft halo around the lines. PNG also supports a transparent background, something a JPG cannot store at all. Converting a photograph from JPG to PNG will not sharpen it, because the detail JPEG removed is already gone. What you gain is a clean, lossless copy you can edit and re-save without wearing the picture down a little more each time. You can drop a mix of .jpg and .jpeg files together, since both are the same format under two names.

Each JPG is decoded into raw pixels, painted onto a canvas, and written back out as a PNG, all on your own device. PNG records every pixel exactly rather than approximating them the way JPEG does, so the picture that comes out matches the JPG you put in, down to the last pixel. Because the file is rebuilt from the decoded image alone, the extra data a camera tucks into a JPG does not come along with it.

One thing to expect is a larger file. Each card in the workspace shows the size before and after, with a small plus-percentage badge when the PNG ends up heavier than the JPG, which is the usual result for a photograph. Nothing is sent anywhere while this happens, so even a long list of photos is handled entirely on your device. Each card keeps the file's own name, so you can tell the photos apart before you convert. The conversion starts only when you press Convert, so you can line up the whole set and remove any you change your mind about before running them.

No. Rebuilding the photo through a canvas writes a fresh PNG that holds only the image, so the GPS location, camera model, lens and timestamp stored in the JPG are left behind. A converted PNG you share does not reveal where the photo was taken or which phone took it.

If you want to see what a file is carrying, open it in the EXIF data viewer and compare the JPG with the PNG. To clean a photo you plan to keep as a JPG, the remove EXIF data tool strips the hidden fields without changing the format.

A PNG is bigger because it is lossless. JPEG was built to make photographs small by throwing away detail your eye is unlikely to miss, so a JPG is already heavily squeezed. PNG keeps every pixel in full and leans on lossless compression, which saves far less on a busy photograph.

Converting a detailed photo to PNG can multiply its size several times over, while a flat graphic with large areas of one colour may grow only a little. If a smaller file matters more to you than a lossless copy, staying with JPG or running the result through compress image is the better route.

With some formats the tool shows a quality slider, because you are trading a little detail for a smaller file. PNG has no such trade to make. It is lossless, so there is no quality dial to turn, and the side panel shows a single PNG output note that reads Lossless output. A small i beside that note explains what lossless means when you tap it.

Every pixel from the decoded JPG is written straight into the PNG. The only real influence on the final size is the picture itself, since a busy photograph packs less tightly than a flat graphic. If you do need a smaller file, the sound way to get one is to convert first, then reduce the size with a separate step rather than degrade the PNG here.

A folder of photos is quicker to handle in one go. Add as many JPG files as you like, then press Convert once. The button carries the count, so it reads Convert followed by the number waiting. An Add images button at the top lets you drop in more before you start, and a small x on any card removes one you did not mean to include. Each photo reports its own size before and after, and the summary line adds up the whole set.

When more than one image is ready, the button becomes Download all (zip) and saves everything as frisqoo_jpg-to-png.zip, with each file keeping its original name and a .png ending inside the archive. A single image gives you a plain Download button instead. Once a batch is done, a short row of cards offers to pass the PNGs straight into another tool, so you can compress, resize, crop or remove EXIF data without saving and adding the files again. The whole set is handled one file after another, so a large batch will not freeze the page while it works. A Share option sits beside the download, so you can send a finished PNG straight on where your device supports it.

The page works the same on a phone as on a computer. Open it in Safari or Chrome, tap the box, choose the JPG photos from your camera roll, then press Convert. Every step runs on the phone itself, so nothing is uploaded and there is no app to install or account to create.

Saving works the usual way for your phone, either straight to Files or Photos or through the share sheet. A big batch of high-resolution photos asks more of an older phone, since the whole job runs in its memory, so convert in smaller groups if the page starts to slow down.

Yes. Many free converters upload your images to their own servers to do the work. This tool does the conversion in your browser instead, so your photos are never uploaded, stored, or seen by anyone else. That makes it a sound choice for personal photos, screenshots, ID scans and anything else you would rather keep off a server you do not control. A private, in your browser note sits at the foot of the page and stays there the whole time you work.

You can check it for yourself. Open your browser's network panel before you convert, run a file through, and watch that no upload takes place while the PNG is made.

People reach for this conversion for a handful of everyday reasons.

• Meeting an upload rule on a site or form that accepts PNG files only.
• Making a lossless working copy before editing the same photo several times.
• Preparing a base image so a transparent background can be added in an editor.
• Turning a whole folder of JPG photos into PNG in one pass and saving them as a zip.
• Handing a clean PNG to a design tool that treats PNG as its default import.
