How to use JPG to PNG

  1. 1

    Add JPG or JPEG files

    Drop up to 10 photos or scans of up to 25 MB each; .jpg, .jpeg and .jfif all work.

  2. 2

    Keep PNG selected

    PNG has no quality setting: every pixel of the decoded JPG is stored as it is.

  3. 3

    Wait a moment

    Each image is written and optimised with OxiPNG; large photos take a few seconds each.

  4. 4

    Download

    Save the PNGs individually, or the whole set as converted-png.zip.

Limits and Pro

Up to 10 JPG files per batch, 25 MB each, kept at full resolution.

Pro converts batches of up to 500 JPG files, each up to 4 GB. See Pro

About JPG to PNG

Converting a JPG to PNG wraps the picture in a lossless format. The pixels you see in the JPG are decoded once and stored exactly, so from this point on the image can be opened, edited and saved again as often as you like without losing any more quality. That is the main reason to do it: JPG degrades a little every time it is re-saved, while PNG never does, which matters when a picture goes through several rounds of editing, annotation or design work.

There are other reasons too. Some apps, slide templates and upload forms accept PNG only; graphics tools that add transparency, such as a background remover, need a format that can store it; and screenshots that were saved as JPG by mistake are easier to annotate as PNG. Photos are turned upright using their orientation tag, colours are converted to sRGB, and EXIF data such as the camera model and GPS location is left out.

Two expectations to correct before you convert. The PNG will be larger, often three to eight times for a photo, because lossless compression can't discard detail the way JPG does. And it will not look better: blockiness, blur and colour banding that JPG compression already introduced are preserved faithfully, because the conversion can only keep what is there. The background stays as it is, too; a PNG can hold transparency, but converting doesn't create it. To cut out the subject and make the background see-through, use the background remover.

Privacy

JPG decoding happens in your browser and the PNG is written by OxiPNG, a WebAssembly optimiser running in a Web Worker in this tab. The photos stay on your device from start to finish and nothing about them is logged.

JPG to PNG: frequently asked questions

Does converting JPG to PNG improve image quality?
No. The PNG is an exact copy of the decoded JPG, so any blur, noise or block artefacts from the original compression stay. What you gain is that no further quality is lost when you edit and save the PNG again and again. If you have the original source of the image, export PNG from that instead.
Why is the PNG so much bigger than the JPG?
JPG compresses photos by discarding fine detail, while PNG must store every pixel losslessly. A typical phone photo grows from 3 MB to 12–20 MB as PNG, even after OxiPNG optimisation. Screenshots and simple graphics grow far less. If size matters, keep the JPG, or choose WebP with Lossless switched on, which is usually smaller than PNG.
Will the PNG have a transparent background?
Not automatically. A JPG has no transparency, so the converted PNG shows exactly the same background, just stored in a format that could hold transparency. To make the background see-through, open the image in the background remover, which cuts out the subject with an on-device AI model and saves a transparent PNG.
Are JPG and JPEG the same?
Yes. JPEG is the name of the standard and its committee, the Joint Photographic Experts Group; .jpg is the three-letter extension that older Windows versions required, and .jpeg or .jfif are other spellings of the same format. This page accepts all of them, and the result is named after the original file with a .png extension.
Is any photo information lost in the conversion?
The pixels are kept exactly, but the metadata isn't: capture date, camera and lens details, and the GPS location are not copied into the PNG. That makes the file safer to share. If you need to keep that information, store the original JPG alongside the PNG, or read the details first with the EXIF viewer.
