Free browser tools — your files never leave your device
Thirty-one fast, free tools for images, PDF, spreadsheets, audio, video, fonts, game development and 3D printing. No watermark, no sign-up, no upload, no daily limit — everything runs 100% inside your browser.
Almost every "free online tool" works the same way: you hand your file to a stranger's server, wait for it to come back, and hope it was deleted. Auctory works the opposite way. Each tool here is a single page that does the whole job on your own machine — with Canvas, WebAudio and WebAssembly — so there is no server for your file to go to.
That changes what you can safely do online. Payroll PDFs, ID scans, customer lists, passport photos, an unpublished thesis, a licensed font, a 3D model you sell, a GPS track that starts at your front door: all of these can be processed here without ever being uploaded. It also means no file-size ceiling, no queue, no "3 tasks per hour", and no account to create.
What we promise
Your file is opened, processed and saved by your own browser. No server receives it, so nothing can be stored, scanned or leaked.
Full-quality output, every time. No account, no e-mail, no "upgrade to download", no daily counter.
When a tool cannot do something well, it says so instead of returning a broken file. Every known limitation is written on the page.
How it pays for itself
These tools are free and stay free. The site is funded by advertising, not by selling your data — there is nothing to sell, because your files are never received in the first place. Analytics are limited to anonymous visit statistics; you can read exactly what is collected in the privacy policy.
Who uses these tools
Marketplace sellers preparing product photos, accountants fixing broken Turkish characters in exported CSV files, graduate students checking thesis formatting before a deadline, HR teams building shift rosters that respect labour law, podcasters and video editors, game developers packing sprite atlases, designers checking whether a font may legally be embedded, and anyone who has ever hesitated before uploading a private document to an unknown website.
