Image Tools
Image tools solve two of the most common image-handling tasks on the web: reducing file size and converting images for inline embedding. The Image Compressor shrinks JPEG, PNG, and WebP files so pages load faster and emails fit within attachment limits, while the Image to Base64 converter produces data URIs you can paste directly into HTML, CSS, or JSON. Both tools run entirely in your browser using the Canvas API, which means your photos are never uploaded to a server — an important property for personal, confidential, or client work. For best results, compress before embedding, and reserve Base64 encoding for small icons and logos rather than large photographs.

Image Tools — Frequently Asked Questions
Are my images uploaded to a server?
No. Both image tools run entirely in your browser using the Canvas API. Your images never leave your device, which makes them safe to use with personal or confidential photos.
What image formats are supported?
The compressor handles JPEG, PNG, and WebP. The Image to Base64 converter accepts any format the browser can decode, including GIF and SVG, and outputs a data URI with the correct MIME type.
Should I embed large images as Base64?
No. Base64 encoding inflates files by about 33% and the result cannot be cached independently. Reserve data URIs for small icons and logos (a few kilobytes); keep large photos as separate, cacheable files.
