Tools

Small tools that don't upload your files

Most online converters ask you to hand over your file, put it on someone's server, and trust them to delete it. These don't. Everything here runs in your browser — there is no server to send anything to.

Image compressor Shrink JPG, PNG and WebP. Resize and re-encode with a quality you choose. Image converter Convert between PNG, JPG and WebP, with control over the background matte. Image cropper Crop to any size or a locked aspect ratio — 1:1, 16:9, 9:16 and more. PDF merger Combine several PDFs into one, in whatever order you like. No quality loss.

Why local matters

When you upload a file to a conversion site, you've given a stranger a copy of it. For a holiday photo that's probably fine. For a signed contract, a passport scan, an invoice or an ID document — which is a lot of what gets fed into PDF tools — it isn't, and no privacy policy makes it not have happened.

Every tool here uses the browser's own file, canvas and blob APIs. Your file is read into memory in the tab you're looking at, processed there, and handed back. Close the tab and nothing remains. You can verify it: open your browser's network panel and watch — there are no requests.

What that costs you

Being honest about the trade: local processing is limited by your device. A 500 MB PDF on an old phone will struggle, where a server with 32 GB of RAM wouldn't. And some conversions genuinely need codecs browsers don't ship — HEIC being the obvious one, which works in Safari and nowhere else.

Where a tool can't do something, it says so rather than failing quietly. That seemed better than pretending.
