Perguntas frequentes
Tudo o que as pessoas costumam perguntar sobre como as ferramentas funcionam, privacidade, formatos e qualidade.
Are my files uploaded to a server?
No. Image conversion and compression run entirely in your browser using the Canvas API, and PDF tools use PDF.js locally. Your files never leave your device.
Is it really free?
Yes. All tools are free with no watermarks, no file limits, and no account required. The site is supported by non-intrusive advertising.
What is the maximum file size?
There is no fixed limit, but very large files depend on your device's memory. Most images and typical PDFs process instantly; very large PDFs may take longer.
Which format should I choose for photos?
JPG or WEBP at quality 80–90. WEBP gives smaller files; JPG gives wider compatibility.
Why does my compressed image look the same but smaller?
Modern lossy compression discards only data the eye is unlikely to notice. At high quality the difference is invisible while the file shrinks significantly.
Does converting remove EXIF metadata?
Yes. Re-encoding an image generates a fresh file from the pixels, leaving the original metadata (including GPS location) behind.
Do the tools work offline?
Once the page has loaded, the core conversion and compression run locally, so they continue to work even without a connection.
Can I convert several images at once?
Yes. The image converter handles batches of up to 20 files in a single operation.
