About this tool

Shrink images for websites, store pages, emails and Discord attachments. Drop a file, pick the output format, lower the quality until the size is right while watching the preview — the file-size readout updates live so you can stop exactly where quality is still acceptable.

Converting a PNG photo to JPG or WebP is usually the biggest single saving (often 70–90 %). Processing runs in your browser; large batches of private images stay on your device.

How to use it

  1. Drop an image (PNG, JPG, WebP, GIF, BMP) onto the page.
  2. Convert & Compress: pick the output format and quality, compare the before/after size, download.
  3. Resize & Crop: choose a social-media or store preset, drag to frame, download.
  4. Favicons: get a ZIP with every standard size plus the HTML snippet.
  5. Palette: read the dominant colours with HEX codes ready to copy.

Frequently asked questions

How much smaller will my image get?

Photos saved as PNG typically shrink 70–90 % when converted to JPG or WebP at 80 % quality. Already-compressed JPGs shrink less; try WebP for a further 20–30 %.

Does compression lose quality?

JPG and WebP are lossy: at 80–90 % quality the difference is invisible for most photos. PNG output stays lossless.

Is there a file limit?

No. Nothing is uploaded, so the only limit is your device's memory.
