Questions, answered plainly.
What happens to your files, what things cost, and where the limits are. If something is missing, ask us.
Privacy and security
Do you upload my files?
Not for 129 of the 133 tools. Those run entirely in your browser through WebAssembly, so the file is read from your disk into the tab and never transmitted. You can verify this in your browser's Network tab: no request carrying your file's size will leave. The remaining tools need real server compute and say so on their own page.
Which tools do send files to a server?
OCR at scale, document translation, structured data extraction, speech transcription and AI image upscaling. Each of those is labelled as server-processed on its tool page, requires signing in, and consumes credits. Nothing else transmits your file.
How long do you keep files that are processed on the server?
Only as long as the request takes. Server-processed files are held in memory to produce the result and are not retained afterwards, and we do not use your documents to train models.
Can I use these tools on confidential documents?
For browser-based tools, yes, because the document never leaves your machine. For the server-processed tools, treat them like any third-party processor and check your own data-processing obligations first. Our guide on whether online converters are safe explains how to tell the two apart.
Do the browser tools work offline?
Yes, once the page has loaded. Because the conversion code runs locally, you can disconnect from the network and browser-based tools keep working. That is also the simplest way to prove nothing is being uploaded.
Accounts and limits
Do I need an account?
No, not for the browser-based tools. There is no signup wall, no email required and no watermark on output. An account is only needed for the server-processed tools, which consume credits, and for the API.
Is there a file size limit?
Browser-based tools are limited by your device's available memory rather than by us, so large files usually work but very large ones can exhaust the tab. The free tier caps server-processed files at 10 MB and 5 conversions per day.
Are there watermarks on the output?
No. Output is never watermarked on any plan, including the free tier.
Pricing and credits
What does it cost?
Browser-based tools are free and unmetered. Pro is $9 per month and includes 900 hosted-tool credits. Business is $29 per month with 2,900 API credits, async jobs, webhooks, teams and white-label embeds. Credit packs can be bought separately.
What is a credit?
A credit is one unit of server-side processing. Each server-processed tool shows its cost per run on its own page. Credits are five cents each in the smallest pack and cheaper in larger packs.
Do credits expire?
Credits bought in a pack do not expire. Credits included with a monthly plan refresh each billing period.
API and embedding
Is there an API?
Yes. The REST API exposes the server-compatible tools, authenticates with an application key, and consumes API credits. Business accounts additionally get asynchronous jobs with signed completion webhooks. The API reference documents every endpoint.
Can I embed a tool in my own site?
Business accounts can embed any tool page as a white-label iframe by adding ?embed=1 to its URL. Embedding is restricted to origins you allowlist, so nobody else can frame your configuration.
