Are images uploaded to a server?
No. All compression happens in your browser using the HTML5 Canvas API. No files ever leave your device. You can verify this by disconnecting from the internet before using the tool.
What image formats are supported?
You can upload JPEG, PNG, WebP, GIF and BMP images. Output can be in JPEG, PNG or WebP format. WebP offers the best compression with high visual quality.
How much can I reduce an image's file size?
It depends on the image type and chosen quality. On average, you can reduce file sizes by 60-80% without visible quality loss. JPEG photos compress best, while PNGs with few colors maintain transparency but reduce less.
Can I compress multiple images at once?
Yes, you can select up to 20 images at once. Each image is compressed individually with the same quality and format settings. You can download them all with one click.
What is the difference between JPEG, PNG and WebP?
JPEG is ideal for photos with many colors, offers good compression but does not support transparency. PNG maintains transparency and lossless quality but produces larger files. WebP is the most modern format: it offers better compression than JPEG and supports transparency like PNG.
Is EXIF metadata removed?
Yes. HTML5 Canvas compression automatically strips all EXIF metadata (GPS location, camera model, capture date). Compressed images contain no personal information — a privacy benefit.
Which quality preset should I choose?
Email (60%): lightweight files for attachments. Web (70%): great balance for sites and blogs. Social (80%): sharp images for Instagram and Facebook. Print (95%): maximum visual quality. You can also choose Custom and adjust the slider manually.
