No tool matches that. Try fewer words or a file format, such as PDF or PNG.
Images
Resize one, shrink one, take out what it quietly records about you, or draw one from nothing - none of it sent anywhere.
- Image Compressor Name the size. It works out the rest.
- Image Resizer Say the size. Draw the box. Pick the format.
- Image Layout Put your pictures together. Keep them on your machine.
- HEIC to JPG The photos an iPhone makes, in a format everything opens.
- WebP to JPG The pictures the web saves, in the format everything still takes.
- PNG to WebP The same picture, often a third off, with the see-through parts intact.
- AVIF to JPG The format websites save now, in the one everything has always taken.
- ID Photo Maker Choose a supported country and document. Published rules and guidance are marked.

- Image Redactor What you cover is deleted from the file, not covered up in it.
- EXIF Viewer & Remover See what a photo says about you. Then take it out.
- DICOM Viewer CT, MR, X-ray and ultrasound, with the window, the header and the measurements.
- Image to ICO One picture in. Every size a browser, Windows or a Mac asks for, out.
- Image to Data URI The whole picture as one line of text. Paste it straight into CSS or HTML.
- SVG to Image Name the size. A vector has none of its own to lose.
- Image to SVG One shape, one outline. Point at whatever should not be there.

- Business Profile Preview Type it, and it becomes the card Google would draw. Nothing is sent to draw it.
Video & animation
Trim, convert or build a clip from photos, with the footage staying on your device.
- Video Compressor Say how big it may be. The tool works out the rest, and measures the result before you get it.
- MP4 Converter Whatever came off the screen recorder, the ripper or the camera, as H.264 and AAC in an MP4. Copied where it can be, re-encoded only where it must.
- Video Rotator A quarter turn, a half turn, the other way. With header rotation, the picture frames stay unchanged.
- Images to Video Make an MP4 from a render sequence, timelapse photos or a slideshow.

- Time-Lapse Maker An hour of footage, in twenty seconds.
- Video Frame Grabber A full-quality still from any point.
- GIF to MP4 Every frame, with the delay the GIF gave it, as H.264 in an MP4. Converted on your machine; the file never goes up.
- Video to GIF Pick the section, the size, and the frame rate.
- GIF Maker Turn a set of pictures into one animation.
- GIF Splitter Extract PNG frames, a ZIP or one sprite sheet, with the timing written down.
- GIF Analyzer Frames, delays, palettes, and where every byte went.

Text, codes & passwords
Read it, check it, or make it here - no token, no config file and no password on somebody else's server.
- JSON Formatter JSON, XML, HTML, CSS and YAML, formatted or converted. Nothing is pasted into anyone else's server.

- QR & Barcode Generator Type it, and it becomes a code. Nothing is sent to make one.
- QR & Barcode Reader Point it at a code, or drop a picture of one. It is read here, and nowhere else.
- Hash & Checksum Check a download against the number the publisher printed, without sending it to anyone.
- Password & Passphrase Generator Made here, by your own browser, and never sent anywhere. Nothing is stored and there is no history.
Connect devices
Share text and files, talk live, or watch a camera or browser tab on another device. Each tool explains what it sends and how the browsers connect.
- Share Text & Files Share text and files from your open browser, encrypted. Direct is the default; Cloud relay is an optional route when devices cannot connect directly.
- Local Walkie-Talkie Start a named channel, then hold to talk or speak hands-free. Connect directly on your local network, or choose Cloud relay for listeners over the internet.
- Voice Oncall Open a pager and hear live voice from people who connect. Use Direct on your local network or choose Cloud relay over the internet, with a password and individual mute or remove controls.
- Remote Camera Open a camera on one device and watch it in another browser, with optional viewer approval. Choose Direct or Cloud relay for encrypted live video.
- Share a Browser Tab Choose a tab on your computer and let one approved viewer watch it using Direct or Cloud relay. Invite by link, network discovery or a private group. No extension, sound or remote control.

Your files stay yours.
Local file processing works offline after the tool is saved. Fetching and sharing require a connection.
How it stays private
- Your files are processed on your device Your browser opens, reads and edits the files you choose. There is no upload for processing. Share Text & Files, Share a Browser Tab, Remote Camera and the live voice tools deliberately send content to another browser; their own pages explain the connection.
- Your files are not given to analytics Page visits, fixed tool-use stages, the first successful result per page load, selected workflow links and optional fixed feedback are counted. No files, filenames, contents or input or output details go with those counts. Optional image imports and receipt exchange-rate requests name their data beside their controls.
- Local processing works offline Wait for a tool's offline indicator to say ready, then disconnect and use files from your device. Fetching a web image, looking up an online rate and connecting two browsers require a network.
None of that has to be taken on trust. How to tell whether a tool really needs your files sets out four checks you can run yourself, on this site or any other.
