Upload a photo, pick a transform and drag the slider to see the exact difference. Nothing leaves your device — all processing runs in your browser.
Choose an image JPG, PNG or WebP · up to 25MB Why side-by-side comparison matters
Compression, grayscale conversion and blur all change your image in ways a thumbnail can't reveal. The interactive slider lets you drag over the exact region you care about — a face, a logo, a background texture — so you can judge quality on your own terms before you commit to a full export from our compressor, blur tool or background remover.
How this tool works
Your file is decoded to an ImageBitmap, drawn to a canvas with the selected filter and re-encoded as JPEG. Nothing is uploaded to a server. Combine this preview with our tools when you're ready for HD output, batch processing or country-specific passport photo compliance.
