About this tool

The Image Compressor reduces JPG, PNG and WebP files using your browser's own encoders. Pick a quality level, compare the result side-by-side, and download — all without a single byte leaving your device.

How to use it

  1. Drop one or more images into the upload area.
  2. Choose an output format and drag the quality slider to taste.
  3. Press Compress and review the before/after comparison.
  4. Download individual results or everything as a ZIP.

Good to know

  • PNG is a lossless format, so PNG output shrinks mainly through re-encoding; converting to WebP usually saves far more.
  • Extremely large images (100+ megapixels) may be limited by available device memory.

Frequently asked questions

Are my images uploaded to a server?

No. Image compression happens entirely on your device — the file never leaves your browser.

How much smaller will my image get?

It depends on the source file. Photos usually shrink by 50–85% at balanced quality; screenshots and graphics that are already optimized may shrink less. The tool always shows you the exact before/after sizes before you download.

Will compression reduce my image quality?

Compression trades some quality for size. Use the quality slider to find your balance — around 80% is visually indistinguishable from the original for most photos. You can also resize dimensions to save more.
