Frequently asked questions
General
Is it free?
Yes. The core tools are free. There is a fair-use limit to keep the service stable for everyone.
Do I need to create an account?
No. You convert right away, no sign-up. Creating an account is optional.
Are my files stored?
No. The uploaded file is deleted right after conversion, and the result is removed automatically within 6 hours.
Is it safe?
The connection is encrypted (HTTPS) and files are not retained. We don't show fake "certification" badges — only what's real: HTTPS and automatic deletion.
How to use
What's the difference between Convert and Optimize?
Convert changes the file format (e.g. PNG → JPG). Optimize reduces the file size while keeping the quality. You can do both at once.
Which formats are supported?
Images (PNG, JPG, WEBP, HEIC, GIF, BMP), videos (MP4, MKV, MOV, WEBM, AVI), audio (MP3, WAV, FLAC, M4A, OGG) and PDF (images↔PDF).
Can I convert several files at once?
Yes. Drop several files and download everything in a single .zip.
Is there a size or quantity limit?
To keep the service stable there are per-batch limits: up to 100 images, PDFs of up to 300 pages and up to 12 adjustments/presets at a time.
