Tip: Select SVG files and set output options before converting. For batch files, only the first 20 are shown for review. All selected files will be converted. AVIF is output with the original filename by default; duplicates get numbers appended.

Choose SVG files

Supports single or batch SVG files. Files are read and converted on this device, with no server upload required.

Click to choose SVG files, or drag files here Supports .svg and image/svg+xml; for batches, the first 20 files are shown.

Waiting for filesAfter selecting SVG files, filenames, sizes, and thumbnails will appear.

Conversion settings

Check quality, transparent background, and size mode first. AVIF encoding is CPU-intensive; increase encoding speed for large batch images.

Quality & transparency Higher quality usually means larger files

Compression mode

Lossy compression Near-lossless

Lossy is good for web images; near-lossless is good for icons, logos, and color-critical assets.

Instructions

Software Usage Instructions

Select SVG files: Click the selection area or drag SVG files into the tool. Batch selection is supported. The interface only displays the first 20 files, but all files will be processed during conversion.
Load sample SVG: For quick testing, click “Load Sample SVG”. The tool will automatically add a sample file and jump to the settings step.
Configure conversion settings:
- Compression mode: Lossy compression is suitable for web images; near-lossless is suitable for icons, logos, and materials with higher color requirements.
- Quality settings: You can adjust image quality and alpha channel quality. The higher the quality, the larger the file usually is.
- Background handling: You can keep a transparent background or specify a background color to fill transparent areas.
- Size settings: Supports keeping the original SVG size, output by scale, custom width and height, proportional fit, fill canvas, and padding.
- Encoding settings: You can adjust encoding speed and chroma sampling. The higher the speed value, the faster the processing.
- File naming: You can add a prefix or suffix and set the ZIP file name; duplicate file names will automatically have numbers appended.
Save settings: After clicking “Save Settings”, the tool will automatically load the current parameters the next time it is opened.
Start conversion: After entering the “Convert & Download” step, click “Start Conversion”. The tool will display processing progress, the number of successful files, the number of failed files, and the result size.
Preview and download: After conversion is complete, you can preview the first 20 results, download AVIF files individually, or click “Download All Results (ZIP)” to save them as a package.

FAQ

A: AVIF is suitable for web assets, icons, logos, interface resources, and images that require transparent backgrounds. It supports lossy, near-lossless, and alpha channels, making it suitable for reducing image size while maintaining visual quality.

A: Yes. Select “Keep Transparent” in the conversion settings to output AVIF with an alpha channel; if you need a white, dark, or brand-color background, you can also choose “Specify Background”.

A: Lossy compression is suitable for web display and file size control, with quality settings between 70% and 85% usually providing a good balance; near-lossless is suitable for icons, logos, line art, and SVG materials that need to preserve details.

A: AVIF encoding is computationally intensive, especially for large images, near-lossless mode, and lower speed levels, which take more time. For batch processing, you can increase the encoding speed value or reduce the output dimensions first.

A: SVG is a vector text format, so source files for simple icons may be very small; AVIF is a raster image, and the output size is affected by pixel dimensions, quality, alpha channel, and graphic complexity. You can reduce the dimensions or quality to make the file smaller.

A: By default, the original filename is kept and the extension is changed to .avif. If duplicate names occur, the tool automatically appends a number to the filename. You can also add a unified prefix or suffix in the settings.
