Software Usage Instructions

Select image files: Click the “Select Images” button and choose the JPG, PNG, WebP, GIF, BMP, or other images you want to convert. You can select multiple images at once.
Set the pixel effect: Adjust the pixel block size. Smaller values make the image more detailed, while larger values make the pixelated grain more noticeable.
Set the color style: Choose to keep the original colors, or select 8 colors, 16 colors, 32 colors, 64 colors, grayscale, Game Boy green scale, NES style, or a custom palette.
Choose dithering and grid: Enable ordered dithering or Floyd-Steinberg dithering for a retro grainy look; add light or dark grid lines if you want a grid effect.
Adjust output settings: Choose PNG, JPG, or WebP format, and set brightness, contrast, saturation, size mode, and export scale as needed.
Preview and process: Click “Preview First Image” to view the effect. After confirming the settings, click “Start Processing.” When batch processing is complete, you can download individual images or download all files as a ZIP.

FAQ

A: For avatars and icons, choose 4-12px; for retro posters, choose 12-30px; for a coarse mosaic effect, choose above 30px. It is recommended to preview the first image first, then adjust based on the image details.

A: The fewer the colors, the stronger the retro style; the more the colors, the more tonal detail from the original image is preserved. 8 colors and 16 colors are suitable for game-style images, while 32 colors and 64 colors are better for preserving more detail.

A: Dithering is suitable for gradients, photos, and images with many color transitions. It can represent more light and dark levels with a limited number of colors. Ordered dithering looks more uniform, while Floyd-Steinberg dithering looks more natural.

A: By default, the original file name is used, with only the selected output format changed. If a duplicate file name is encountered, a number is automatically appended to the file name to avoid overwriting the result.

A: You can use “Limit long edge” to reduce the output size, or increase the pixel block size. If you have many images to process in batches, it is recommended to process them in smaller batches and download the ZIP file promptly after processing is complete.

A: No. Image reading, pixelation, previewing, and exporting are all done locally, and files are not uploaded to the server.
