PNG, JPEG, static WebP or BMP. 40 MiB/file, 24 MP, 8192 px/side; pixel operations 6 MP. GIF: 120 frames and 24 MP across all frames. Split: at most 256 pieces.
Checkerboard areas indicate transparency. Previews fit the screen; downloads keep the displayed pixel dimensions.
Details
Image exports re-encode pixels; Base64 encode/decode preserves original bytes. BMP 1/4/8/16-bit and GIF reduce colors. BMP 4/8-bit palettes use up to 8/128 colors. JPEG fills transparency.
IMAGE WORKSPACE
Understand the task
Image analysis separates encoded file properties from decoded pixels. The original file size is measured in bytes, dimensions in pixels, and exact color frequencies include alpha. A fully transparent red pixel and fully transparent black pixel count separately when the decoder preserves their hidden RGB values.

How to use
- Choose the operation that matches your task. Import a file, try the example, or enter text for generation and Base64 decoding.
- Adjust the visible settings and create a preview. The original remains available. Changing settings disables the old download until you run again.
- Inspect the result, details and dimensions. Copy text when available or download the file. Use the alternate download for PNG, extracted frames or a second representation.
Limits and common errors
Decoding can normalize colors and transparent pixels. Reported frequencies describe the browser-decoded image, not every original encoding detail. Hex/RGB exports are row-major pixels; original file bytes include headers and compression. These are different representations.
