Compress PNG
Compress PNG without uploading it
Load a PNG and shrink it two honest ways: strip the metadata chunks (text, timestamps, EXIF) for a pixel-identical file, or resize it and let the browser re-encode the pixels. PNG is lossless - there is no quality knob - so real savings come from fewer pixels, never from guessing. Everything runs on this page: no upload, no server, no library.
- PNG is lossless - there is no quality slider here, so size only falls when pixels or metadata go.
- Strip metadata removes text chunks, timestamps and EXIF without touching a single pixel.
- Resizing is the strongest lever: half the pixels is roughly half the file.
- Photographs rarely belong in PNG - use this tool for screenshots, art and graphics.
- Palette PNGs with 256 colors or fewer expand to full RGB on re-encode and can grow.
- Browsers re-encode with their own compression settings, so results differ slightly between them.
- Transparency survives a resize, but color profiles and metadata are dropped by the re-encode.
- Interlaced PNGs come out as normal non-interlaced files after a resize.
- A PNG that oxipng or pngquant already tightened has little left to remove here.
- Nothing is uploaded - the file is read, rewritten and downloaded inside this tab.
- Check the result size before downloading: if it grew, lower the scale and run it again.
