About QuickImager
A privacy-first image converter that runs locally in your browser. No uploads, no accounts, no drama.
Principles
Built Around 3 Principles
Privacy, speed, and compatibility.
Private By Default
Conversions run on your device. Your images are not uploaded to a server, and nothing is stored.
Fast, Not Flashy
WebAssembly-powered image processing for near-native performance without waiting on uploads.
Practical Compatibility
Convert to formats you can actually use on the web and across apps, with sensible defaults.
How It Works
Most online converters upload your files to a server. QuickImager does the opposite: it processes files locally.
Drop Your Files
Drag and drop up to 20 images (or click to browse).
Pick An Output
Choose a format and any options like quality or metadata stripping.
Download Instantly
Download per-file or as a ZIP. No accounts, no wait.
Formats
Inputs include common images plus HEIC, PDF, and SVG. Outputs focus on broadly useful image formats.

Privacy note
Files are processed on your device. The only analytics used are aggregate Cloudflare Web Analytics (cookieless, no user profiling).
No ads, no account gates, no dark patterns — just a clean tool that respects your time and your data.
Tech Stack
Built with modern web tooling and proven open-source libraries.
WebAssembly + libvips
High-performance image processing in the browser.
SvelteKit
Fast routing, static output, and clean UI composition.
PWA Friendly
Works offline after the app and any required libraries have loaded once.
Why Not Upload?
Uploading is slower and introduces privacy risk. Local processing keeps your files on your device.
Better privacy
No third-party storage and fewer opportunities for leaks.
Faster workflow
No upload time. Conversions start immediately.
Works in more situations
After the app is loaded once, it can keep working with limited connectivity.
