Keys are stored in this browser only. A key lets you buy credits and keep going after the free runs.
How it works
- Choose a file with the file picker and set your target format, dimensions and any quality or metadata options.
- Press Run; the tool converts and resizes the image according to your settings.
- When the result appears, inspect it and download the converted file.
Limits
Each input file may be up to 10 MB; the output may be up to 25 MB; images may not exceed 50 million pixels, and animated files are capped at 300 frames. Twenty runs a day are free with no login required. After those, each run costs 1 credit drawn from a prepaid balance tied to an API key.
Privacy
Your input is processed for the request and discarded immediately afterwards; it is not kept or used for anything else. Usage records store only the time, tool name, status, duration, credits used and a salted hash of the IP address.

Questions
Which formats can I convert between?
The tool accepts and produces PNG, JPEG, WEBP, GIF, BMP, TIFF and ICO.
Are my files stored after conversion?
No. The input is processed for that request and discarded; nothing is retained.
How do I call this from code?
Send a POST request to https://data.voiddo.com/v1/image_convert — a curl example is shown on this page. The page form and the API use the same endpoint.
What happens once I have used the twenty free runs?
Each additional run costs 1 credit from a prepaid balance attached to your API key.
What does stripping metadata do to colours?
When you choose to drop EXIF, XMP and ICC data, colours are converted to sRGB first so the image still renders correctly on screen.
