Image Tools
Toolisco’s image tools cover the everyday work of preparing pictures for the web and for documents: converting between formats, shrinking file size, resizing to exact dimensions, turning images into Base64 or data URIs, and reading or removing embedded metadata. Because everything runs on your own device using the browser’s native image APIs, your photos are never sent to a server.
What this category covers
This category groups tools that read, transform, or generate raster and vector images. That spans format conversion (JPG, PNG, WebP, AVIF, SVG), compression and resizing, colour work, QR and barcode handling, and utilities that encode an image into text so it can travel inside HTML, CSS, or JSON.
Common use cases
- Shrinking photos to meet an upload size limit while keeping them sharp
- Converting a PNG to WebP or AVIF to cut page weight
- Inlining a small icon as a data URI to save a request
- Stripping GPS and camera data from a photo before sharing it
- Reading a QR code from a screenshot instead of a camera
Best practices
- Resize to the final display dimensions before compressing, so you are not spending bytes on pixels no one sees.
- Prefer modern formats such as WebP or AVIF for photographs, with a fallback where older browser support matters.
- Keep an original copy before optimising, in case you later need a higher-quality version.
- Check a photo for embedded location data before publishing it publicly.
