What this tool does

Compress images to reduce their size while keeping the visible quality. Perfect for speeding up your site load or freeing up storage space.

If the image is too large, first run it through image resize. To switch to WEBP, use image converter.

What you can use it for

  • Lighten photos before uploading them to a blog or online store.
  • Compress heavy screenshots so they fit through email.
  • Reduce image weight to improve mobile performance.
  • Move JPG photos to WEBP without sacrificing visible quality.

How to use it

  1. Drag an image into the box or select several.
  2. Adjust the quality: 75 to 85 is a solid starting point.
  3. Pick the output format or leave it on Auto to keep the original.
  4. Press Run and download the compressed version.

Everything runs inside your browser. No file is uploaded to any server. See more tools in this field.

Tricks for compressing well

Compression is not magic: you lose some quality. These tips help you squeeze the most weight out without it showing on screen.

  • Start at quality 80

    On JPG and WEBP, 80 is where savings are big and the loss is still invisible to the eye. Drop to 70 if the image can handle it, but always check the most detailed area.

  • Compress once

    Every compression adds loss. Keep the original and compress from there when you change something, instead of compressing over an already compressed file.

  • Resize before compressing

    A 4000 px photo displayed at 800 px on screen carries 5x more weight than needed. Resize first, then compress.

  • WEBP wins for web

    For a public site, WEBP at quality 80 usually leaves the file 25 to 35 percent lighter than the JPG equivalent, with the same apparent sharpness.

Frequently asked questions

How much can the file size drop?

It depends on the content and source format. For JPG photos at quality 80, expect reductions of 40 to 60 percent. WEBP, compared to the original JPG, usually shows reductions of 25 to 35 percent with the same visual quality.

Is it lossy or lossless compression?

Lossy, but the loss is practically invisible above quality 75. The tool uses the native browser encoder, which is well tuned for that range.

Is WEBP always the right choice?

For the web, yes, in most cases. If the image has to be compatible with older software, prepared for print or used in pipelines that don't support WEBP yet, JPG is still the safe option.

Do I lose quality if I compress again?

If you recompress an already compressed image, quality drops a little more every time. The recommendation is to compress once, starting from the original.
