About SizoKit

SizoKit is a free collection of online file tools: compress and resize images, convert HEIC photos to JPG, turn images into PDF, merge or compress PDF files, and convert video and audio such as MOV to MP4, MP4 to MP3, WAV to MP3 and video to GIF.

We built it because everyday file jobs should not need an account, an install or a watermark. Every tool is free, works on phones and computers, and is designed to be quick: pick a tool, drop your file, download the result.

Privacy first

Image and PDF tools run in your browser, so your files never leave your device. For heavier jobs (video, audio, PDF compression, HEIC) the file is sent securely to our server, processed, and deleted immediately afterwards. Read the privacy policy for details.
