Image tools

Image work that never leaves this tab.

Uploads are read with the File API and drawn to a canvas on your device.

Download the result locally. Nothing is posted to Pocket Caliper servers.

Image CompressorShrink JPEG, PNG, or WebP files with a quality slider. Compression uses canvas in your browser so the original never uploads.
Image ResizerResize images to exact pixel width and height, with an option to keep the aspect ratio. Processing stays on this device.
JPG to WebPConvert JPEG photos to WebP in the browser to cut page weight. Adjust quality, then download the .webp without uploading.
PNG to WebPConvert PNG graphics and screenshots to WebP for smaller assets. The file is encoded in your browser with a quality control.
WebP to JPGConvert a WebP image to JPEG when a tool, email client, or printer still needs JPG. Encoding happens locally on this device.
