Convert JPG to PNG - Free Online

What this tool does

Convert JPG to PNG in your browser. Output is a lossless PNG suitable for editing or layering. Batch-convert multiple files and download as a ZIP.

Private browser-based processing

Your images are processed locally in your browser. Files are not uploaded to PhotoTools.org servers, and the finished result is generated on your device.

When to convert JPG to PNG

PNG is lossless. Once you convert a JPG to PNG, any further edits and re-saves will not add new compression artefacts. That makes PNG the right intermediate format for layering, retouching, annotating, or combining a photo with overlays.

Common situations: prepping a photo for Photoshop or GIMP, building a thumbnail with text on top, exporting a JPG into a graphic-design pipeline, or freezing a copy before running further edits that you do not want to repeat from the original.

The lossy-to-lossless conversion

Converting a JPG to PNG does not improve the source. JPG has already discarded detail in the compression step, and PNG cannot recover what is no longer there. What PNG does is preserve the JPG's current state without adding more loss.

If you plan to edit the file, this matters. Re-saving a JPG many times stacks compression artefacts. PNG flattens that risk: you can edit, save, and edit again without further degradation.

File size expectations

PNG files are usually larger than the JPG source, often by a factor of two to ten depending on content. PNG compresses well for graphics with flat regions but is much less efficient than JPG for photographs.

If size matters, keep the original JPG for sharing and use the PNG only for editing. Or convert to WebP, which supports lossless mode and stays much smaller than PNG.

How the conversion works in your browser

The tool decodes the JPG using the browser Canvas API and re-encodes it as a PNG. PNG output is lossless, so the converted file is a pixel-perfect copy of the decoded JPG. The entire process runs on your device with no upload.

EXIF metadata is dropped during re-encoding, which is usually a positive side effect: the new PNG no longer carries the camera, lens, or GPS data that was attached to the original JPG.

Batch convert and ZIP download

When you have a folder of JPGs to convert for editing or archival, drop them all in at once. Each appears as a card with its own status. Click Convert all to process the entire batch in one pass.

When the conversion finishes, the bottom bar lets you download every converted PNG as a single ZIP. This is the fastest way to bundle a batch for an editing project, a layered Figma file, or an archive.
