All tools
17 tools, every one of them running entirely in your browser. Deliberately a short list: each of these is meant to be the best way to do that one thing, not a checkbox on a feature comparison.
Images
Convert, compress, resize and clean up photos without them leaving your device.
HEIC to JPG
Turn iPhone HEIC photos into JPGs that open anywhere.
PNG to JPG
Turn PNG screenshots and exports into much smaller JPGs.
JPG to PNG
Turn JPGs into lossless PNGs for editing or transparency work.
WebP to JPG
Turn WebP images from the web into JPGs older software can open.
JPG to WebP
Shrink images for the web without a visible quality drop.
Compress Image
Make photos smaller for email and uploads, without a visible quality drop.
Resize Image
Set a maximum width or height and scale photos down in one pass.
Remove EXIF
Strip GPS coordinates, camera details and timestamps — without re-compressing.
Split, merge, rotate and export PDFs locally — including the ones you would never upload.
PDF to JPG
Render every page of a PDF as a JPG image.
PDF to PNG
Render PDF pages as lossless PNGs with crisp text.
Image to PDF
Combine photos and scans into one PDF, in order, on your device.

Pull out the pages you need, or break a document into single pages.
Rotate PDF
Fix sideways scans and save the rotation permanently.

Utilities
Small everyday tools for files and text. Same rule: nothing is sent anywhere.
What is deliberately missing
Some conversions cannot honestly be done in a browser, and adding them would mean adding a server — which would end the only thing that makes this site worth using. Word and Excel conversion, OCR of scanned documents, video transcoding and anything needing a rendering engine are all in that category. Where a genuinely good in-browser implementation appears, the tool will appear with it. Until then we would rather be short a feature than short an architecture.
