Step 2
Select Services
Resize Settings
Choose target dimensions and whether ImageWorks should preserve the original aspect ratio.
Compression Settings
Control output quality. For PNG Smaller File mode, this controls color reduction strength.
HEIC Conversion Settings
Convert iPhone HEIC/HEIF files locally in this browser to JPEG or WebP.
Remove Background Settings
Prepare background removal for local browser processing. Final output will use transparent PNG when Remove BG is active.
Upscale Settings
Increase image resolution locally in the browser. This engine uses high-quality canvas scaling and does not upload images anywhere.
Watermark Settings
Add a text watermark, an image/logo watermark, or both. Everything is rendered locally on canvas.
Live Watermark Preview
This preview updates before processing. It is a visual guide; the final watermark is rendered on each selected image.
Estimated Output
These estimates are calculated before processing. Actual size can vary by image content and browser encoder.
Add Images and services to preview likely output size.
ImageWorks processes Compress, Resize, Watermark, PNG handling, WebP, estimates, previews, and ZIP downloads locally in your browser. HEIC conversion works when the local decoder is installed. Remove BG uses the browser AI engine when available. Upscale runs locally using the browser canvas engine.
