Frequently asked questions
Quick answers about how this tool works.
Are my images uploaded anywhere?
No. All compression happens locally in your browser using the Canvas API. Your files never leave your device.
Is the compressor free?
Yes — fully free, unlimited, no account, no watermarks.
Will my image lose quality?
JPG, WEBP and AVIF use lossy compression, so some quality is traded for smaller files. Use the quality slider to find the sweet spot. PNG is lossless — most savings come from re-encoding and stripping metadata.
How small can I make my images?
Pick a target file size (in KB) and we'll auto-tune quality to get as close as possible while preserving the best look.
Is EXIF metadata removed?
Yes — re-encoding strips EXIF, GPS coordinates and camera tags, which also reduces file size.
Does it work on mobile?
Yes. The compressor is fully responsive and runs on any modern phone, tablet or desktop browser.
