How to use this JPG to PNG converter
- Drop your JPG or JPEG photos into the box above, or press Browse files to select them.
- Review the queue, file names and sizes are listed so you can spot a wrong pick immediately.
- Press Convert to PNG. PNG has no quality setting, so there is nothing to tune.
- Check the size change reported beside each finished image.
- Save each PNG individually, or download the batch as a single ZIP file.
Why use this converter
- Accepts both .jpg and .jpeg spellings, plus files whose extension does not match their real type.
- Produces true lossless PNG output. No second round of compression damage.
- Converts a queue of twenty photos in one pass with a live progress bar.
- Reports the size difference honestly, including when the PNG ends up considerably larger.
- Drops the JPEG's embedded EXIF block, so camera and location metadata does not travel with the copy.
- Runs offline once loaded, because there is no server involved at any stage.
What you gain by moving from JPG to PNG
JPEG was designed in an era when storage was scarce and photographs were the only thing anyone put on a screen. It compresses by discarding information the eye tends not to miss, and it does that again every single time the file is saved. Open a JPG, crop it, save it, reopen it, adjust the levels, save again, after a handful of rounds the edges pick up a mushy halo and flat skies develop faint blocks.
PNG breaks that cycle. It stores exactly what it is given and returns exactly that on reopening. Converting a JPG to PNG cannot undo the damage already baked into the file, but it freezes the image at its current state so no further generation loss accumulates. For anything you intend to keep editing, that is worth the extra megabytes.
Practical reasons people make this switch
- Preparing a photo as a working master before a long editing session in an image editor.
- Meeting an upload requirement, plenty of forms, badge systems and print portals accept PNG only.
- Placing a photograph into a design file alongside graphics that are already PNG, to keep the asset folder consistent.
- Sharing a screenshot that happens to have been captured as JPG, where text edges look softer than they should.
- Stripping the EXIF block from a phone photo before publishing it, since the conversion discards it automatically.
The trade-off is file size
Be ready for the numbers. A 2 MB JPEG photograph frequently becomes an 8 to 12 MB PNG. Lossless compression has to encode every pixel that survived the original lossy pass, and photographic detail is close to random from an algorithm's point of view. There is no setting that avoids this. It is the nature of the format, not a shortcoming of this page.
If the resulting file is impractical to email or upload, you have two sensible options. Run it through the PNG compressor, which reduces the palette where it can do so invisibly, or reconsider whether PNG was needed at all. For a photograph that will simply be viewed rather than edited, staying with JPG and using the JPG compressor almost always gives a better result per kilobyte.
Metadata quietly disappears
A JPEG straight from a phone carries an EXIF block: camera model, exposure settings, the date, and often the GPS coordinates where the shot was taken. When this tool redraws the photo onto a canvas, that block is left behind, the canvas only receives pixels. The PNG you download therefore has no camera data and no location attached.
That is a privacy win in most situations and an inconvenience in a few. If you were relying on capture dates to sort an archive, note them before converting. If stripping metadata is the actual goal and you want to keep the JPG format, the EXIF remover is the more direct tool for the job.
Nothing leaves your device
Every step happens inside this browser tab. The File API hands your photo to a canvas, the canvas re-encodes it, and a download link is created from the result in local memory. No copy is transmitted, cached on a server or queued behind other people's jobs, which is why a batch of twenty runs as fast as your own processor allows. Related conversions such as PNG to JPG and HEIC to JPG follow exactly the same local-only design.
