Compression Tools

Compress text or a file with gzip, deflate, brotli or Zstandard and see the size before and after, the compression ratio and how long it took. One click tries every method and recommends the smallest result.

Decompress gzip, deflate, brotli or Zstandard data from a file or pasted Base64 and read the result as text or download it. Detects the format from the magic bytes where possible, with a manual override.

Compress images to JPEG at a target file size or quality, with presets for WhatsApp, Instagram and Discord, optional resizing and EXIF kept or stripped.

Shrink a PDF's file size by re-encoding its pages at a chosen quality and resolution. See the size before and after, preview the result, and tune the quality until size and readability balance.

Shrink an SVG with SVGO. Paste the markup or drop a file, toggle every optimizer plugin individually, set the numeric precision and multipass, and compare the size before and after. Copy the result or download it as a file.

Compress a video to a quality level or a target size like 10 MB, scale it down if you like, and compare the size before and after with a preview.
