./prontouso.com is a small, independent project, and there is a real person on the other side of this address. Write in English or Portuguese — both are read.

Replies usually take a few days. This is not a staffed support desk, so please be patient with the turnaround.
What to write about
- Something is broken
- A tool returns a wrong result, a page fails to load, or something behaves oddly in your browser. Telling us which browser and which tool helps a lot.
- You want a tool that is missing
- The catalog grows based on what people actually need. Suggestions for new tools, or for options missing from an existing one, are genuinely useful.
- A question about privacy or your data
- Anything about how the site handles information, including requests under the LGPD or the GDPR.
- Business, press, or partnership
- Advertising enquiries, collaborations, or anything commercial.
About this form
Your message is stored in our restricted internal database until an administrator reads and deletes it — see the Privacy Policy for retention details. It is never shared with third parties or used for anything other than replying to you.
Before you write about a tool
For almost every tool, what you type or paste never reaches us, so we cannot look up what you were working on. (Image Compressor, Image Resizer, PDF Merge, Split & Image to PDF, Image Format Converter, OCR — Image to Text, Video Compressor, HEIC to JPG Converter, MP4 to MP3 Converter, Animated GIF Compressor, Background Remover, Image Upscaler & Enhancer, PDF Compressor, Word to PDF Converter, Password Breach Checker, Security Headers Scanner, Sitemap XML Validator's optional "Fetch from URL", YouTube Thumbnail Downloader, DNS Propagation Checker, SSL/TLS Certificate Checker, and YouTube Tags Extractor process what they receive on our server for a single request and then discard it, so we still cannot retrieve it afterwards.) If you are reporting a wrong result, including the input you used — when it is not sensitive — makes the problem far easier to reproduce. Never send us passwords or confidential files.
