About this tool
The Image Compressor re-encodes JPEG, PNG, and WebP images in your browser to reduce file size. You can adjust quality, resize dimensions, and convert between formats. The original file stays on your device — nothing is uploaded.

Frequently asked questions
Are my photos uploaded?
No. Compression happens entirely in your browser using Canvas and encoder APIs.
Which format should I pick for the web?
WebP usually offers the best size-to-quality ratio. JPEG is the safest fallback when broad compatibility is required.
Why did my PNG get bigger after compression?
PNG is lossless and already well-compressed. Try WebP or JPEG for photographs to shrink further.
What happens with EXIF metadata?
Re-encoding strips most metadata including location. Re-attach EXIF with another tool if you need to keep it.
