How ImgLab Works
Unlike traditional online tools that upload your files to remote servers for processing, ImgLab takes a fundamentally different approach. Every tool on this site uses client-side web technologies — specifically the HTML5 Canvas API for image processing, pdf-lib for PDF creation/manipulation, and pdfjs-dist for PDF rendering.
When you drop an image or PDF into one of our tools, the file is read directly into your browser's memory using the FileReader API. All transformations (compression, resizing, format conversion, cropping, filtering, etc.) happen inside your browser's JavaScript engine. The processed result is generated locally and made available for download — without a single byte ever being sent over the network.
This architecture means ImgLab works offline once the page is loaded, has zero file size limits (constrained only by your device's RAM), and offers true privacy — we couldn't access your files even if we wanted to, because they never reach our servers.
What You Can Do with ImgLab
- Optimize images for your website — Compress photos, convert to WebP, and resize to exact dimensions to make your pages load faster and rank higher in search results.
- Prepare images for social media — Crop to platform-specific ratios (1:1 for Instagram, 16:9 for YouTube), add watermarks to protect your work, and resize to recommended dimensions.
- Protect your privacy — Strip GPS coordinates, camera information, and other metadata from photos before sharing them online. ImgLab's metadata tool shows you exactly what data is embedded in your images.
- Manage PDF documents — Merge multiple PDFs into one, reorder or delete pages, compress large files for email, convert PDFs to images, or create PDFs from your photos.
- Edit images quickly — Rotate sideways photos, apply filters for quick enhancements, draw annotations or highlights, and pick colors from any image for your design projects.
Frequently Asked Questions
Is ImgLab really free?
Yes — all 15 tools are completely free to use with no limits, no watermarks, and no account required. ImgLab is funded through non-intrusive advertising. You can even refuse cookies and still use every tool without restrictions.
Are my files safe?
Absolutely. Your files never leave your device. All processing happens locally in your browser using JavaScript. There are no uploads, no server-side processing, and no data transmission. You can verify this by checking your browser's Network tab in Developer Tools while using any tool — you'll see zero file uploads.
Does ImgLab work offline?
Yes! Once any tool page is loaded in your browser, you can disconnect from the internet and continue using it. All the processing code runs locally, so no network connection is needed after the initial page load.
What image formats does ImgLab support?
ImgLab supports JPEG, PNG, and WebP for all image tools. The format converter additionally supports SVG vectorization (converting raster images to scalable vector graphics). HEIC/HEIF (iPhone photos) is not supported due to patent licensing restrictions.
Is there a file size limit?
There is no hard file size limit since everything runs locally. The practical limit depends on your device's available RAM. Most modern devices handle images up to 50 megapixels and PDFs up to 100+ pages without issues. Very large files may take longer to process on older or mobile devices.
How do we stay free?
ImgLab is funded by advertising, not by selling your data. We don't collect, store, or have access to your files — ever. Your images are processed locally in your browser, and our revenue comes solely from ads displayed on the page.
If you accept cookies, ads may be personalized based on your browsing interests. If you refuse, we only display contextual ads based on the page content — with zero tracking, zero cookies, and zero profiling. Either way, your images are never accessed or transmitted.
