Compress images
Make an image smaller, change its format, or scale it down. Camera metadata is stripped on the way through. Files are processed in memory and never written to disk.
By optimising an image you agree to the Terms of Service and the Acceptable Use Policy, and you confirm you hold the rights to what you upload. Files are processed in memory and never stored; see the Privacy Policy.
Free online image compressor and converter
A photo straight off a phone is several megabytes of detail that no web page, email or chat window will ever display. Re-encoding it at a sensible quality, and scaling it to the size it will actually be seen at, usually removes most of that without a visible difference.
Metadata is dropped in the process. Photos carry EXIF that can include the exact coordinates where they were taken, and stripping it is the right default for a tool people hand personal pictures to.
Frequently asked questions
Is the image compressor free?
Yes. Compressing and converting is free. There is no signup, and nothing is watermarked or held back behind a paywall.
Which format should I pick?
WebP is the usual answer: clearly smaller than JPEG, supported everywhere current, and it keeps transparency. AVIF is smaller still but slower to encode. JPEG is the safest for anything old. PNG is lossless and much larger.
Why is HEIC not offered?
HEIC relies on HEVC, whose patents are not licensed for commercial server use. AVIF gives comparable file sizes using AV1, which is royalty-free, so it is offered instead.
Is EXIF data removed?
Yes. Metadata is stripped during re-encoding, which includes GPS coordinates, camera details and timestamps. That is the safer default for photos taken on a phone.
What happens to transparency when I convert to JPEG?
JPEG cannot store transparency, so transparent areas are filled with white rather than turning black.
