Free TinyPNG Alternative That Supports AVIF, HEIC, and WEBP

Stop Paying for Image Compression

Most developers reach for TinyPNG out of habit. It works — but it only compresses JPEG and PNG, and cannot output modern formats like AVIF or WEBP.

AT USE Compress Image is a free, server-side alternative that handles six formats.

What It Supports

• Input: JPEG, PNG, WEBP, AVIF, HEIC (iPhone photos), TIFF
• Output: JPEG, PNG, WEBP, AVIF, BMP, TIFF
• Quality slider: 1 to 100 for fine-grained file size control
• Metadata strip: removes EXIF data before sharing
• Server-side processing via ImageMagick — handles HEIC natively

Where TinyPNG Falls Short

TinyPNG cannot output AVIF or WEBP. AVIF achieves 30 to 60% smaller file sizes than JPEG at equivalent visual quality, with broad browser support since Safari 16.4.

How It Works

1. Upload your image (up to 20 MB)
2. Set your quality target
3. Pick the output format
4. Download — the file is deleted from the server after download

Nothing is stored. No account required.

When to Use It

• Compressing product images before uploading to a CMS
• Converting iPhone HEIC photos to web-safe JPEG or WEBP
• Generating AVIF variants for picture elements in your HTML
• Stripping EXIF location data before posting images publicly
