This tool blends the painted area with nearby pixels to soften/blur it — works best on simple text or light watermarks; results on complex backgrounds won't be perfect. Only use this on your own files.
For PDFs: edit this page, press "Save this page", then switch to another page to edit that one too. When you're done, "Download PDF" saves the whole file — untouched pages stay at their original quality.

This tool interpolates pixels to increase resolution/size, like an "upscale" in photo editing — detail that wasn't in the original file won't appear in the new pixels either, the image will just be bigger and a bit smoother.

Click and drag on the photo to select the crop area.
Choosing a Passport/ID/PAN preset auto-fills the output size (you can still change it). Crops are always made from the original photo's full resolution, not the smaller on-screen preview.

This tool re-draws and re-saves the photo, which automatically strips hidden EXIF details like camera model, date/time, and GPS location. Visual quality is unaffected.

Compression re-renders every page as an image and rebuilds the PDF, so the result won't have selectable/searchable text (it's a visual copy only). If keeping selectable text matters, try the "Low" level or skip compression.

Metadata found in this PDF
After cleaning
The actual content (text, images, pages) stays exactly the same — only the document's "properties" (author, title, software info, dates) are removed, and any hidden XMP metadata block is stripped too.

This runs peer-to-peer over WebRTC, browser-to-browser — there's no game server. A free public signalling service is used just to help you connect; great for casual games with friends, not built for heavy scale.

🎲
Your files are never uploaded
Every tool on Seal — watermarking, compressing, converting, cropping, all the PDF tools — runs entirely inside your own browser using JavaScript (canvas, pdf-lib, pdf.js). The photo or PDF you choose is never sent to any server. Close the tab, and everything is gone.
What we store
Only two small preferences are saved in your browser's localStorage — your theme choice (day/night) and language choice (English/Hindi). Both stay on your own device and are never sent anywhere.
Google Sign-In
The Google sign-in button in the sidebar is entirely optional and only shows your name/photo — it isn't required to use any tool. Sign-in is handled by Google's own service (accounts.google.com); we never see your password or account data.
Third-party libraries
When the page loads, a few open-source libraries (pdf-lib, pdf.js, JSZip, QRCode.js) are fetched from a public CDN (cdnjs.cloudflare.com), and Google's sign-in script from accounts.google.com. Those requests only fetch library code — your files or their contents are never sent to them.
Tracking or ads
This site does not include any analytics, tracking scripts, or ads.

Free PDF & Image Tools — No Sign-Up, No Uploads
Seal is a free online toolkit for working with PDFs and images — merge, split, compress, and watermark PDFs, or convert, resize, and edit photos. Every tool runs directly inside your browser, so there's nothing to install and no account to create. Your file never leaves your device.
The flow is simple: drop in your file (or click to choose one), let the tool process it, and download the result right away. There's no login, no waiting for an upload to finish, and no queue — because the file is never sent anywhere. Processing happens locally using pdf-lib, pdf.js, and your browser's built-in canvas APIs.
