Online image editor, Base64 encode/decode, and image format conversion (png, jpg, webp, svg).
This page holds three jobs: convert a format, turn an image into Base64, and edit.
Upload a PNG, JPG, or WebP and pick the output format. Use it to shrink a photo to WebP or to turn a screenshot into JPG before you attach it. The single-purpose page is /image/convert.
Encode builds a data URI you can paste into a small CSS or HTML file. Decode goes the other way: paste the string and read the mime type and size. If the declared mime does not match the bytes, the panel says so. Convert and Base64 send the file to the Utilsbox API and do not store it as an account.
Crop, adjust, and export in the editor. The image is not uploaded to a host: the crop runs in the browser. To merge pages or rotate a PDF, use the PDF hub, not this screen.
For photos, almost always. For a flat icon with few colors and transparency, a small PNG can win. Compare the size the tool reports before you replace the file.
No. It is the same file written as text. On a page with many images it weighs more than a cached file, because it cannot be cached apart from the HTML.
On the PDF hub, PDF to images. This page works on image files, not on PDF pages.
