About AVIF Compression
AVIF (AV1 Image Format) is the next-generation image format that offers exceptional compression efficiency. AVIF files can be up to 50% smaller than JPEG with the same quality. Our AVIF compression tool helps you optimize these cutting-edge image files for the best web performance. Ideal for modern websites and applications that support this advanced format.Before emailing a PDF, open the downloaded copy and check fine text at the intended viewing size. The tool can reduce image detail; its target size is not guaranteed. If forms, signatures or searchable text matter, keep the original PDF.

Frequently Asked Questions
How much smaller can AVIF files get compared to JPEG?
AVIF files are typically up to 50% smaller than JPEG at the same visual quality. Compared to PNG, savings often reach 70-80%. Actual results depend on image content: photos with flat colours compress more dramatically than highly detailed photographs.
What is the maximum AVIF file size I can compress?
Our tool accepts AVIF files up to 50 MB each, with a maximum batch of 20 images per session. Images above 4K resolution are automatically downscaled only if you choose that option; otherwise, original dimensions are preserved during compression.
Does compressing an AVIF image reduce its quality?
Compression uses lossy optimisation that targets visually identical output. At the default quality setting, most users see 30-60% size reduction with no noticeable difference. You can adjust quality between 10 and 100 to balance file size against image fidelity before downloading.
Can I compress multiple AVIF files at once?
Yes. Batch mode lets you queue up to 20 AVIF files simultaneously. Drop them all into the upload area, and the tool processes each one independently, delivering a ZIP archive of compressed images when the batch finishes.
How long does it take to compress an AVIF image?
A typical 2 MB AVIF image compresses in 3-5 seconds. Larger files, such as 20 MB images, may take 15-30 seconds. Batch jobs of 20 images usually complete in under 2 minutes, depending on your internet upload speed.
Which browsers support AVIF images?
AVIF works in Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+, covering roughly 93% of global browser usage. Older Safari versions (15 and below) cannot display AVIF, so keep JPEG or WebP fallbacks for maximum compatibility.
Do I need to install software to compress AVIF files?
No installation is needed. The compressor runs entirely in your browser and works on Windows, macOS, Linux, Android, and iOS. Just open the page, drop your AVIF files, and download the optimised results, with no account required.
Is it safe to upload my AVIF images for compression?
Yes. Uploads travel over an encrypted HTTPS connection, and all files are automatically deleted from our servers within one hour of processing. No images are shared, indexed, or used for any other purpose.
Why Choose Let Compress?
- Compare the downloaded file’s quality and actual size.
- Savings vary by file. Some tools return the original if the output is larger; check the resulting format and size.

Adjust image quality or dimensions. Lossy output can change fine detail; preview text and edges before using it.
There is no guaranteed saving or exact target for every file. If the result is larger, some tools return the original; compare its format and size before sharing. Before emailing a PDF, open the downloaded copy and check fine text at the intended viewing size. The tool can reduce image detail; its target size is not guaranteed.
