Image Compressor & WebP Converter (No Upload)

Compress images and convert them to WebP without uploading anything - re-encoding also strips GPS and other EXIF data automatically.

What it helps with

  • Shrink photos before attaching them to email or forms
  • Convert images to WebP for a faster website
  • Strip GPS location from photos before sharing

How to use

  1. Drop image files or choose them from your device.
  2. Pick the output format, quality, and an optional long-side limit.
  3. Compare the sizes and download each file or all of them.

Examples

Phone photo to WebP

Input

photo.jpg (4.2 MB)

Output

Output

screenshot-compressed.webp (210 KB)

Good to know

  • Compression is lossy for WebP and JPEG output; keep the originals.
  • PNG output is lossless, so it can be larger than the source.
  • Bulk download saves files one by one; ZIP export is not supported yet.
  • Animated images are compressed as a single still frame.

FAQ

Are my images uploaded to a server?
No. Compression runs on this page with your browser's canvas API. The images never leave your device.
Is EXIF data such as GPS location removed?
Yes. Re-encoding through the canvas produces a clean file without EXIF metadata, which is safer for sharing photos.
Why is my PNG output larger than the original?
PNG is lossless, so re-encoding cannot always shrink an already-optimized file. Choose WebP or JPEG for strong compression.
