About ImageConvert
ImageConvert is an image conversion and compression platform built by web performance engineers since 2021. We focus on one thing: making image optimisation fast, private, and accessible — no account required, no files uploaded, no guesswork.
Built by web performance specialists since 2021
The ImageConvert team has been working on web performance tooling since 2021. Our tools are used daily by developers, content teams, marketers, and designers who need reliable image format conversion without friction. Every feature — from the quality slider to the bulk ZIP download — is driven by real workflow feedback and performance measurement.
We run the conversion directly in the browser using the Canvas API, which means your files never leave your device. There are no server uploads, no third-party processing, and no logs of what you convert.
Benchmark methodology
The file size comparisons published on our PNG to WebP page are based on real conversions performed by the ImageConvert team using the same browser-based Canvas API that powers the tool itself.
| Parameter | Value |
|---|---|
| Conversion engine | Browser Canvas API (canvas.toBlob with image/webp) |
| Browser used | Chromium 123 (headless) |
| Lossy quality setting | 85 (the tool default) |
| Lossless mode | Canvas quality parameter omitted (browser decides) |
| Image types tested | Photo, logo, screenshot, illustration, icon |
| Source format | PNG (8-bit RGBA) |
| Measurement tool | Blob.size property after conversion |
| Number of samples | 5 images per category, results averaged |
Results represent averages across representative samples. Actual savings vary by image content, source quality, and browser version. Lossless savings align with Google's published 26% average reduction for WebP lossless vs PNG.
What we built
The platform supports format conversions between PNG, JPG, and WebP, plus strict compression to exact kilobyte targets (100 KB, 200 KB) for forms and portal uploads that enforce hard size limits. We designed every tool for speed: most conversions complete in under one second because nothing leaves the browser.
