Privacy workflow
Review, clean and finish before export
The native apps combine visual anonymization, metadata control and upload preparation in one reviewable workflow.
License plates
Review plate candidates in photos and videos
A dedicated scan proposes possible license plates without automatically selecting or covering them.
- Inspect every proposed plate before applying an effect
- Choose pixelation, blur or a black cover
- Preview video tracks before exporting the result
Faces & visible text
Cover only what you choose
Privacy Cleaner suggests face and visible-text regions in photos and videos. You review the candidates and decide what to cover.
- Pixelate, blur or cover selected regions in black
- Use an eye bar or emoji for selected faces
- Add manual photo regions and review sampled video tracks
Metadata & GPS
Control information hidden inside files
View, edit or remove supported metadata fields and location information before sharing a file.
- Inspect supported EXIF and GPS information
- Edit or remove supported fields

Smart Fix
Turn upload rules into a prepared file
Smart Fix reads maximum size, required format and pixel dimensions from a screenshot or photo, then prepares matching supported files on your device.
- Target KB, MB, format and pixel requirements
- Compress supported PDFs and Office documents
- Compress or convert supported images, video and audio
Detection results are suggestions, not a guarantee of complete recognition. Small, blurred, moving or briefly visible content can be missed, so always review the preview before export.
Questions
FileSizeFix privacy and platform FAQ
Are my selected files uploaded for processing?
No. Selected files and their contents are processed on the device in the native apps or locally in the browser and are not uploaded to a server for file processing.
Does FileSizeFix find every face, text region or license plate?
No. Detection creates candidates for your review and can miss content. Android bundles candidate detection for Latin, Chinese, Devanagari, Japanese and Korean scripts; other scripts and small or blurred content can be missed. Always check the preview before sharing.
What is the difference between the apps and web tools?
The native apps include Privacy Cleaner, plate review, supported metadata controls, Smart Fix and editing such as PDF annotation and signing. The free web tools focus on local browser compression and conversion.
Can every file reach an exact size target?
Not always. File content and format limit how far it can be reduced safely. FileSizeFix shows the result so you can verify size, quality and readability before using it.
