Practical Use Cases & Tool Combinations
Combining tools lets you protect privacy and process images efficiently in a single workflow.
Check and remove privacy risks before posting to social media
Start with Privacy Checker to see what data your image contains. If GPS location is found, strip it with Remove EXIF. If readable QR codes, barcodes, or text appear in the image, redact them with Mask & Redact before posting.
Reduce file size for email attachments
Lower the resolution with Resize, then convert to JPEG or WebP for high compression. File size drops dramatically while quality stays acceptable. Since processing happens in the browser, it works even on throttled connections.
Redact sensitive areas in business documents before distribution
Redact names, addresses, and stamps from scanned documents with Mask & Redact, remove metadata with Remove EXIF, then convert to PDF for distribution. Everything stays in the browser — sensitive documents never leave your device.
Optimize product or food photos for the web
Crop to frame the subject, resize to web-appropriate dimensions (e.g. 1200px wide), then convert to WebP for better PageSpeed scores. No network traffic during processing — batch large numbers of photos quickly on your device.
Create an animated GIF from multiple images
Trim each frame with Crop, standardize dimensions with Resize, then generate an animated GIF with Image to GIF. Adjust frame intervals to create stop-motion or smooth loop animations.
Single-Tool Use Cases
Remove home or workplace location from real estate or travel photos
Remove GPS coordinates, capture timestamps, and camera model from photos with Remove EXIF. Run it before posting to social media or auction sites to prevent others from pinpointing your home or workplace.
Use Remove EXIF →Redact part of an ID or certificate before submission
Use Mask & Redact to precisely black out specific fields on driver's licenses, national ID cards, or other documents. The edited image is saved as a new file — your original is untouched.
Use Mask & Redact →Comprehensive privacy check before any upload
Privacy Checker scans for GPS data, EXIF, QR codes, barcodes, and readable text all at once. Use it as a habit check before sharing any image externally.
Use Privacy Checker →Fix rotated or incorrectly oriented scanned images
If scanned or photographed documents appear sideways, use Rotate & Flip to correct the orientation before converting to PDF or printing.
Use Rotate & Flip →What Is EXIF Data — And Why It Matters
EXIF (Exchangeable Image File Format) is metadata automatically embedded in photos by digital cameras and smartphones. It can include:
- GPS latitude, longitude, and altitude (your exact location)
- Capture date and time (revealing when and where you were)
- Camera or smartphone model and serial number
- Technical parameters: lens info, exposure, ISO
Use Remove EXIF before uploading to social media or sending as an email attachment to eliminate the risk of third parties reading this data.
Frequently Asked Questions
- What data do smartphone photos typically contain?
- Most smartphone photos include GPS coordinates (latitude/longitude), capture timestamp, and device model. Use Privacy Checker to see exactly what is embedded.

- Yes. Remove EXIF only strips metadata. The visual content, resolution, and quality of the image are not affected.
- What is the maximum image file size?
- The general guideline is 50 MB per file, though it depends on your browser's available memory.
