Bring your images.
Choose a file, a batch, or a folder. Your original files remain untouched.
Compress static AVIF images in your browser. Keep AVIF output, review image quality and dimensions, and download individual results or a batch ZIP.
Your image format stays the same. Drag and drop, or choose images below.
Bring your AVIF files and prepare them for modern web images where efficient encoding matters. Your files stay on your device throughout processing.
PikoZip encodes AVIF locally and supports transparency. Encoding may take longer than JPEG or WebP, especially on a phone.
Check your destination’s accepted formats. File size and visual quality vary with the image; AVIF does not win every comparison.
Try Auto Optimize if you want to compare formats instead of choosing a format in advance.
Choose a file, a batch, or a folder. Your original files remain untouched.
Set format, quality, width, and an optional target size. Compare your result.
Download one image or the whole batch in a ZIP, with folder paths preserved.
No image bytes are uploaded. Your browser fetches the image codecs, then processes your selected files locally.
Savings vary. A same-format, same-dimension original is retained when it is smaller. Explicit conversions may increase file size, which the result clearly shows.
Yes. PikoZip does not overwrite the source file on your device. Keep your original master and download the output as a separate file.
Compare four PNG modes and WebP/AVIF exports with original fixtures, exact file bytes, decoded-pixel checks and a transparent reproduction method.
