File tools

Small utilities for working with files, free and without an account. They all run in your own browser: whatever you open stays on your device, and nothing is uploaded.

Available now

• File hash & checksum generatorWork out the SHA-256, SHA-1 or MD5 of a file and check it against the one the publisher gave you. The file is read in your browser and never uploaded.
• QR code generatorMake a QR code for text, a link or your Wi-Fi network, and download it as a PNG or an SVG. Nothing you type is sent anywhere.
• Image compressor & resizerShrink and resize photos, convert between JPEG, PNG and WebP, and take the set as a ZIP. Every image is processed on your own device.
• Video frame extractorPull JPEG stills out of a video at the frame rate you choose. No upload, so no size limit and no copy left on a server.
• Stylish name generatorFancy Unicode text for a display name, grouped by how likely each style is to survive being pasted — with the length in characters, UTF-16 units and bytes.
• Instagram data download viewerRead the messages in your Instagram export without uploading it or unzipping it, with conversations split across several files merged back into one timeline.
• Join .001 files, and split filesPut .001/.002 parts back into the original file, with nothing to install and no size limit — and cut a file into parts the same way.
