Free Image Compressor

For most web images, 75-85% quality is the sweet spot: visually indistinguishable from the original, but significantly smaller in file size. For social media, 80% works great. For print or archiving, stay at 90%+.

WEBP produces smaller files at the same visual quality compared to JPEG, and is supported by all modern browsers. Use WEBP for websites and web projects. Use JPEG for maximum compatibility with older software or if the recipient might use the image in other applications.

No. Compression happens entirely in your browser using the Canvas API. Your image never leaves your device.

PNG is a lossless format — it cannot be lossy-compressed like JPEG or WEBP. To reduce PNG file size, convert it to WEBP using the Image Converter tool instead.
