Image tools that never leave your browser
A focused set of compression and conversion tools for specific, real problems — exam upload limits, iPhone photos that won't open on Windows, screenshots that are bigger than they should be. Every tool runs entirely on your device.
No uploads. No accounts. Nothing leaves your device.
Compress to an exact size
Tell it the KB limit a form actually enforces, and it works backwards to the best quality that fits — instead of you guessing at a quality slider.
- Compress an Image to 100KB
Compress any photo to under 100KB in your browser — a practical size for web uploads, CMS media limits, and faster-loading pages, with no quality slider to fuss over.
- Compress an Image to 200KB
Compress a photo to under 200KB without obvious quality loss — a good target for profile pictures, portfolios, and uploads that need to still look sharp.
- Compress an Image to 50KB
Shrink any JPG, PNG, or HEIC photo to under 50KB right in your browser. No uploads, no signup — built for application forms, exam portals, and email limits.
- Compress a JPG to 20KB
Shrink a JPG photo or signature to under 20KB for exam portals and government forms — entirely in your browser, no uploads.
- Compress a PNG to 100KB
Shrink a PNG screenshot, logo, or graphic to under 100KB while keeping transparency and sharp edges — PNG compression works differently than JPG, and this tool is built for it.
- Reduce Image Size in KB
Pick your own target file size in kilobytes and compress any photo to fit, instead of guessing at a quality percentage — works for any specific KB limit a form or site gives you.
Convert between formats
Fix a file that won't open somewhere, or get the format you actually need for editing, printing, or transparency.

Convert AVIF images to JPG in your browser — fixes files that won't open in older browsers, photo editors, or email clients that don't yet support AVIF.

Convert iPhone HEIC photos to JPG instantly in your browser. No uploads — fixes the 'this file can't be opened' problem on Windows, email, and old websites.

- Convert JPG to PNG
Convert a JPG to PNG in your browser when you need a lossless copy for editing, or a format that supports adding transparency.
- Convert PNG to JPG
Convert PNG images to JPG in your browser to cut file size dramatically — ideal for screenshots and photos saved as PNG that don't actually need transparency.
- Convert PNG to WebP
Convert PNG images to WebP in your browser to cut file size while keeping transparency — a good move for website images and faster page loads.
- Convert WebP to JPG
Convert WebP images to JPG in your browser — fixes files that won't open in older software, email clients, or upload forms that don't recognize WebP.
- Convert WebP to PNG
Convert WebP images to PNG in your browser — for older software that can't open WebP, or when you need to preserve transparency in a more widely-supported format.
