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
A pixel effect changes neighboring colors or maps brightness to a new pattern. Blur averages detail, sharpening increases local contrast, and Floyd–Steinberg dithering distributes black-and-white error to nearby pixels. Choose the effect that fits the intended output rather than stacking unrelated filters.
What this tool does
Blur · Sharpen · Pixelate · Add noise · Floyd–Steinberg dither · Two-color threshold · Find edges · Color mosaic · JPEG compression artifacts · Solid redaction rectangle
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
Blur and pixelation are visual effects, not reliable removal of confidential information. Use a fully opaque solid rectangle for sensitive regions and check the downloaded file. A region can retain its original alpha outside the selection.
