Solution
Resize images in a GDPR-friendly way — without uploads
Many compression services upload your images to the cloud — along with filenames, EXIF, and sometimes GPS coordinates. ConV processes everything locally in your browser.
Resize and re-encode happen entirely on your device using WebAssembly codecs and parallel Web Workers. Your server never receives image bytes.
Your visitors get smaller files and faster page loads while you keep full custody of the data. Great for public websites, intranets, and storefronts with strict requirements.
Key benefits
- No image uploads — pixels never leave your device
- EXIF and GPS metadata stripped automatically on re-encode
- Batch resize multiple images at once with ZIP export
- Works offline once the tool is loaded
Common use cases
- Agencies resizing client photos under NDA
- Healthcare teams preparing patient-adjacent imagery
- Public sector teams with strict data minimization policies
- E-commerce teams resizing product images in bulk
How it works
- 01
Drop your images — JPEG, PNG, WebP, or AVIF
- 02
Choose target dimensions and output format
- 03
Workers encode in parallel using WASM codecs
- 04
Download individual files or a ZIP archive — all from your device
Limitations and realistic expectations
Best-effort metadata removal — not all codec variants or container formats are covered. Validate output files before submitting to contexts with strict metadata requirements.
Frequently asked questions
Are my images uploaded to a server?
No. All processing happens in your browser using WebAssembly. No image data is transmitted to ConV servers.
Does resizing strip EXIF and GPS data?
Re-encoding through ConV removes metadata in most cases. Validate output files if metadata-free output is a hard requirement.
Can I resize multiple images at once?
Yes. Drop a batch, set your target size, and export a ZIP with all resized files.
Does ConV guarantee GDPR compliance?
ConV provides a local processing architecture that supports data minimization. You remain responsible for your legal compliance obligations.

Remove EXIF data and GPS timestamps — locally
Camera metadata can contain sensitive information: GPS coordinates, device identifiers, timestamps, and software versions. Re-encode in your browser to strip this data before sharing.
Compress locally instead of sending files to the cloud
Classic online compressors are convenient but not always compliant for sensitive work. ConV keeps originals on your device; outputs are built with WASM encoders right in the tab.
GDPR-friendly image compression without image uploads
Sending employee or client images to a third-party cloud API creates data processing questions. ConV avoids this entirely: the compression pipeline runs in your browser — your images never reach ConV servers.
