Image Compressor
Drop an image, pick a quality, compare sizes, download. Everything stays on your device.
Frequently asked questions
How much smaller will my image get?
Photos typically shrink 60-90% at quality 70-80 with no visible difference at normal viewing sizes. Screenshots and graphics with text compress less as JPEG; try WebP output for those.
Which output format should I choose?
WebP usually gives the smallest files at equal quality and is supported by every modern browser. Use JPEG when the file must open in older software; use PNG only when you need lossless quality or transparency.
Are my photos uploaded anywhere?
No. Compression runs on your device using the browser's canvas. The image never leaves your computer, which also makes this faster than upload-based compressors.
Does compressing remove EXIF/location data?
Yes. Canvas re-encoding strips metadata, including GPS location — a privacy bonus when sharing photos publicly.
