❓ FAQ

How does conversion work?
Pick images, choose a target format, adjust quality or resize, then tap Convert. Once done, tap Save to Photos or Share. Converted images are stored temporarily in the app.
What does the quality slider do?
Controls compression for lossy formats (JPEG, WEBP, HEIC). Higher = better quality, larger file size. PNG, TIFF, and BMP are lossless — the slider is hidden for those.
How does resize work?
Set a max width and/or height. The image scales down proportionally — aspect ratio is always preserved. Fill only one field and the other auto-calculates.
What about my privacy?
Everything runs on-device. No images, usage data, or personal information ever leaves your phone. No analytics, no tracking, no servers. The app requests photo library access only to pick and save images.
