Choose the format for your image
A photo, a logo and a screenshot have different needs. Start with the format that suits your content.
AVIF
AVIF can make detailed photographs small. Encoding takes more time; compare fine textures and gradients before downloading.
Read the guideWebP
WebP balances file size and processing speed. It supports transparency and works well for everyday web images.
Read the guidePNG
PNG suits logos, illustrations and screenshots. Use lossless compression for exact pixels, or palette reduction for smaller graphics.
Read the guideJPEG
JPEG is a familiar choice for photos. It does not support transparency; transparent areas use a white background.
Read the guideA few things worth knowing
Will my images be uploaded?
No. The site downloads its compression tools, then processes your images locally. Selected image bytes are never sent to a server.
Is compression always lossless?
No. The default balances size with visual detail. For exact PNG pixels, enable Lossless PNG. The comparison tool helps you choose the right tradeoff.
Which format should I choose?
AVIF often gives compact photographic images but takes longer. WebP offers a useful balance. PNG suits graphics and transparency. JPEG is widely compatible but cannot keep transparency.
Is there a file limit?
There is no paid tier or daily quota. Your browser’s memory and device speed still matter. Very large images and animated images may be rejected rather than silently changed.
