Image Tools

Twelve image tools that run entirely on a canvas in your browser: resize, compress, convert, crop, watermark and more. Your photos are never uploaded — every pixel is processed on your own device.

Resize, compress and convert without uploading

The Image Resizer scales photos to exact pixel dimensions or a percentage, and the Image Compressor shrinks JPEG and WebP file sizes with a quality slider and a live before/after comparison, so you can find the smallest file that still looks right. The Image Converter switches between PNG, JPEG and WebP. Most sites offering these operations upload your file to a server first; here the work happens in your browser through the canvas API, which is faster for large photos and means a private photo stays private.

Several tools in the category target developer chores specifically. The Favicon Generator turns one image into a complete favicon set — a real .ico file plus every PNG size a web manifest asks for. The SVG to PNG Converter renders SVG markup or files to crisp PNG at any scale, with no rasterizer to install. And the Image to Base64 Converter produces a data URI with ready-to-paste HTML and CSS snippets, useful for inlining small icons and shaving an HTTP request off a page.

Edit photos and strip hidden metadata

The Image Cropper, Image Rotate & Flip and Image Watermark tools cover quick edits: drag a crop selection with free-form or fixed aspect ratios, rotate in 90° steps or mirror an image, and stamp a text watermark with control over position, size, color and opacity. The Image Color Picker reads any pixel’s hex code from a photo and extracts its dominant palette. Before a photo goes public, the Image Metadata Remover strips its EXIF data — most phone photos quietly carry GPS coordinates, camera details and timestamps. The Image Measurement Tool completes the set: calibrate a known length on a photo or plan, then measure real distances across it.

Frequently asked questions

Are my images uploaded to a server?

No. Every image tool here reads your file locally and processes it on a canvas element in your browser; the result is downloaded straight back to your disk. Nothing is transmitted, which you can verify by using any of the tools with your internet connection switched off.

Will resizing or converting reduce image quality?

Resizing down always discards pixels — that is the point — but it is the re-encoding format that decides visible quality. PNG output is lossless, while JPEG and WebP are lossy, which is why the Image Compressor gives you a quality slider and a live before/after view so you can judge the trade-off yourself.

What exactly does the Image Metadata Remover strip out?

EXIF metadata: GPS coordinates of where the photo was taken, the camera or phone model, timestamps, and assorted camera settings. The pixels are untouched — you get the same image, minus the data you probably didn’t know you were sharing.
