Output settings

Target format

"Auto" re-encodes in the original format; BMP, GIF and ICO have no modern counterpart and are normalized to PNG.

Quality

Applies to JPG, WebP and AVIF output. Around 80% is the sweet spot between size and fidelity.

PNG is lossless and ignores the quality slider — the resulting file size is determined by the image content itself.

New settings apply to the whole batch only after you click here.

Every conversion happens inside your browser. Images are never uploaded to any server.

When converting JPG to PNG makes sense

A JPEG-to-PNG conversion does not add detail — the data was already discarded by the JPEG encoder. What it does give you is a file that will not degrade further each time an editor saves it, plus compatibility with tools and workflows that only accept PNG.

It is the right move before heavy editing: cropping, compositing or repeated saving of a JPEG slowly accumulates artifacts, while PNG keeps the current pixels exactly. Just remember the pixels you start with are already the compressed ones.

Expect the file to get bigger, often 3–10×. If the goal is a smaller delivery file, keep the JPEG or convert to WebP instead; this page is about compatibility and editing, not size.

How to convert JPG to PNG

Add JPEG files

Drop files or a folder into the workspace. Output is already locked to PNG.

No quality setting needed

PNG is lossless, so the quality slider is disabled. Resize first if the PNG would otherwise be impractically large.

Download

Save individually or as a ZIP, ready for an editor, an upload form or an archive.

Questions about this task

Does PNG conversion improve JPEG quality?

No. The compression artifacts are already baked into the pixels. PNG only stores them exactly, which prevents further loss during editing but cannot restore what was removed.

Why is the PNG so much larger than the JPG?

JPEG throws away perceptual detail; PNG keeps every pixel. For photos this means 3–10× more data. Keep the JPEG for delivery and use PNG only when editing or compatibility requires it.

Can I convert back to JPEG later without losing more quality?

Each JPEG save is lossy, so quality drops a little every time. Work in PNG while editing, then export a single final JPEG at the quality you need.
