Built for everyone who works with files
We started Zestools with a simple idea: powerful file tools should be free and easy for everyone.
Our Story
Zestools was born out of a simple frustration: why do you need to download heavy software, pay for subscriptions, or deal with watermarks just to convert a video or compress a PDF? We believed there had to be a better way.
We started by building a handful of essential conversion tools and quickly realized how much demand there was for a clean, fast, and honest platform. Today, Zestools offers 80+ tools covering everything from video conversion to AI-powered image editing — all accessible directly from your browser.
Our team is a small group of developers and designers passionate about building tools that are genuinely useful, fast, and respectful of your privacy. We don't show ads, we don't sell your data, and we don't add unnecessary friction.
What We Offer
Four powerful categories covering every file task you need.
Convert
Convert between any format — MP4, MP3, PDF, DOCX, PNG, GIF, and more. Our converters are fast, lossless where possible, and support batch processing.
Compress

Edit Tools
Crop, resize, rotate, flip, merge, split, protect, and organize your files. Dozens of powerful editing tools that work directly in your browser.
AI Tools
Remove backgrounds, upscale images to 4K, transcribe audio and video to text, generate images from text, colorize old photos, and more — powered by AI.

Every tool is optimized for performance. Files are processed on a high-performance VPS server with 96GB RAM, FFmpeg, and dedicated GPU support. Most conversions complete in seconds.

We do not read, analyze, or share your files. Uploaded files are automatically deleted from our servers within 1 hour. No one at Zestools has access to your content.
- 🆓
Free and Fair
The core tools are always free. We offer a Pro plan for power users who need higher limits and advanced AI features — but we never lock basic functionality behind a paywall.
