About Image Optimizers

Smaller images, same picture

Large images slow down websites, bounce off upload forms and fill up phones. An image optimizer removes the data your eyes do not notice, so a 4 MB photo can often become 300 KB with no visible difference. This collection covers every common case: general compression, an exact target size for online forms, format specific optimizers, and presets for websites, shops and social media.

Compress to an exact size

Government portals, job sites and exam forms often accept only files under a fixed limit. Pick the matching tool and it finds the best quality that fits: compress image to 20KB, 50KB, 100KB, 200KB and more, up to 1MB.

Compress by format

Optimize for where the image goes

Website, mobile, e-commerce, social media, thumbnail and retina optimizers apply sensible sizes and quality for each use. For privacy, the metadata remover strips EXIF and GPS location before you share a photo.

Alternatives to TinyJPG and TinyPNG

Used to TinyJPG or TinyPNG? The TinyJPG alternative recompresses JPG photos and the TinyPNG alternative shrinks PNG files, both in your browser, with no upload, no account and no limit on the number of files.

Tips

  • Resize before you compress: a 4000 pixel photo on a 1200 pixel wide page wastes most of its bytes.
  • Use JPG or WebP for photos and PNG for logos and text.
  • Compress once from the original; recompressing a compressed JPG adds blocky artifacts.
