Image compressor
Drop images in, get them back smaller — WebP or JPEG, resized to the width you need, with a quality slider and a before/after size for each. It all happens in your browser; nothing is uploaded anywhere.
How it works
- Drop one or more images (PNG, JPG, WebP, GIF, up to 50 at a time) or pick them with the button.
- Choose the format (WebP is 25–35 % smaller than JPEG at the same look; JPEG for old mail clients), the largest width you need (1600 px is plenty for a full-width web image, 800 for a blog body) and the quality (80 is the sweet spot).
- Each file shows the original size, the new size and the saving. Download them one by one or all at once.
- The work is done by your browser's canvas — the files never leave your computer, so this is fine for screenshots with customer data.
Questions people ask
WebP or JPEG?
WebP for the web: every current browser reads it and it is a third smaller. JPEG when the image goes into e-mail, a Word document or an old CMS. PNG only for images with transparency or sharp text — and even then WebP does both smaller.
What quality should I use?
80 for photos and screenshots is visually lossless for almost everyone. 70 if the page is image-heavy. Below 60 you start to see it on text.
Does it keep transparency?
WebP yes. JPEG has no transparency — transparent areas become white.
Why is the PNG output bigger?
PNG is lossless, so the slider does not apply; for photos it is always large. Pick WebP.
Is metadata removed?
Yes — the canvas drops EXIF (location, camera, date), which is usually what you want before publishing a photo.
