Powerful image tools — free, fast and private

Piclizer is a free online toolbox that brings more than 70 everyday file utilities into one fast, private website. Instead of installing heavy desktop software or uploading documents to anonymous cloud servers, you open a tool, drop in a file, and get the result in seconds — while the file itself never leaves your device.

Every tool is organised into nine clear categories: image compression and resizing, format conversion (including iPhone HEIC photos), PDF merging and splitting, text cleanup, practical calculators, and a full suite of developer utilities. Each tool page explains exactly what the tool does, which formats it accepts, how to use it step by step, and answers the questions real users ask — so you always know what will happen before you start.

Behind the simple interface is a deliberate engineering choice: all processing runs locally in your browser using modern web standards. That is why Piclizer is free, why it works even on a slow connection once the page has loaded, and why your photos, contracts and code stay yours. No account, no email required, no watermark on your output.

We publish practical guides — from compressing images without visible quality loss to preparing passport photos that meet official requirements — because we believe a good tool should also teach you something useful. Whether you are a student, a photographer, an office professional or a developer, Piclizer is designed to be the fastest path from "I have a file problem" to "done".
