About ImageTools
ImageTools is a collection of 15 free image utilities built around one principle: your files stay on your device.
What we built and why
Most online image tools work by uploading your files to a remote server, processing them there, and sending them back. That approach works, but it raises real questions: Who has access to those files? How long are they stored? What happens if there is a data breach?
We built ImageTools differently. Every operation — resizing, compressing, converting, cropping, rotating, adding a watermark — runs entirely inside your web browser using JavaScript. Your images are never transmitted anywhere. They never touch our servers because we do not have servers involved in the processing pipeline at all.
The tools
ImageTools covers the most common image tasks people search for every day:
- Resize — pixel-perfect dimensions with aspect ratio lock, presets for Instagram, YouTube, Facebook, and more
- Compress — quality slider or automatic compression to a specific file size target (50KB or 100KB)
- Crop — free-form or fixed aspect ratios (1:1, 4:3, 16:9, 9:16)
- Rotate and flip — correct orientation issues in seconds
- Convert — PNG↔JPG, HEIC to JPG (iPhone photos), images to PDF
- Watermark — add text or logo branding with opacity and position control
- Government form photos — auto-resize and compress to PAN card, UPSC, SSC, and passport specifications
How it works technically
When you drop an image onto any tool, it is read directly by your browser using the File API. Processing is done through browser Canvas APIs, WebAssembly libraries like pica for high-quality resizing, and format-specific converters like heic2any for HEIC files and jspdf for PDF generation. The result is generated as a Blob in memory and offered to you as a download — all without a single HTTP request carrying your image data.
Heavy libraries (HEIC converter, PDF generator) are loaded on demand only on the pages that need them, so the homepage and other tools stay fast.
