How to use this page
- Drop your photo into the box above. The cat 2025 photo preset is already loaded.
- (Optional) Crop manually if you need to focus on a specific area of the image before compression. Skip this step if the photo is already framed correctly — the tool will auto-centre-crop.
- Click "Compress to spec". The tool resizes, and compresses to land inside the official file-size band.
- Download and submit to your application portal.
Your photo never leaves your device. Compression runs entirely in your browser using the Canvas API and a Web Worker. We do not store, log, share, or even see your photos — there is no server-side processing.
What the tool does not check
- Plain white or off-white background (verify by eye before submitting)
Verify these manually against your form's official guidance before submitting.
