About ImgTurbo
A focused browser image converter with a small, explicit feature set: one JPEG, PNG or WebP image, transformed on the visitor's device.
What ImgTurbo is for
ImgTurbo handles quick raster conversion and basic pixel transformations without creating an account or sending the source file to an image-processing backend.
Resize and orient
Scale by percentage or dimensions, rotate, flip and create a grayscale copy within the published memory limits.
Measure
See the real output format, dimensions, bytes and percentage difference before downloading.
The processing boundary
The application uses the browser's image decoder, Canvas API and encoder. The source image is represented in browser memory and is not included in an HTTP request to ImgTurbo. The page itself is still delivered by a web server, and consent-based analytics can load for visitors who accept it.
| Inputs | One JPEG, PNG or WebP that the browser can decode |
|---|---|
| Outputs | JPEG, PNG and browser-supported WebP |
| Limits | 30 MB source file, 40 megapixels, 16,384 pixels per side |
| Not included | Batching, animation preservation, RAW/HEIC/PDF/vector conversion, metadata preservation or professional color management |
Operated by Dynamic Foundries
ImgTurbo is operated by Dynamic Foundries, a French SASU registered with RCS Paris under number 102 801 206. European operation and local image processing are trust facts; the main promise remains a practical, transparent converter.
Method and sources
- MDN documents that Canvas always supports PNG and uses PNG when a requested type is unsupported.
