Compress JPG

Efficiently compress JPG files to speed up page loads and improve site performance. Advanced algorithms keep strong visual quality while reducing size—ideal for web design, email attachments, and social sharing.

Compress PNG

Compress PNG online with lossy or lossless modes while preserving transparency. Essential for designers and developers who need smaller transparent assets without sacrificing clarity.

Compress Images

A general compressor for JPG, PNG, WebP, and more. Smart algorithms shrink file size while preserving quality—helpful for optimizing entire sites and saving storage.

WebP to JPG

Convert WebP to widely supported JPG when older devices or platforms cannot display WebP. One click for viewing, editing, and sharing anywhere.

WebP to PNG

When you need transparent WebP assets in tools that only accept PNG, convert losslessly while keeping the alpha channel intact.

PNG to JPG

Turn PNG into smaller, more compatible JPG when transparency is no longer needed—a common step for faster uploads and everyday sharing.

HEIC to JPG

A must-have for iPhone users: convert HEIC photos to JPG so they open on Windows, Android, and the web without compatibility issues.

HEIC to PNG

Convert HEIC to high-quality PNG for design workflows that may need transparency or maximum fidelity.

AVIF to JPG

Bridge AVIF compatibility gaps by exporting to JPG so highly compressed images display everywhere.

AVIF to PNG

Preserve transparency from next-gen AVIF by converting to PNG—reliable for design and publishing pipelines.

JPG to WebP

Modernize the web stack: JPG to WebP can cut size by up to ~70% with minimal visible loss, improving speed and SEO.

PNG to WebP

For transparent PNGs, WebP often delivers smaller files with the same alpha support—best practice for performance-focused sites.

JPG to PNG

Move from lossy JPG to lossless PNG when you need further editing without extra degradation, or for print-quality output.

JPG to AVIF

Experience next-generation compression: JPG to AVIF can beat WebP on size for cutting-edge performance goals.

PNG to AVIF

Upgrade PNG to AVIF for transparency, HDR, and extreme compression when your audience supports the format.

Compression Quality

Applies when the target format is JPG, WebP (lossy), or AVIF (lossy).

Lower values mean smaller files and more visible loss. We recommend 75 as a balanced default.

If the file is still too large, try lowering resolution—it often helps more than quality alone.

Resolution

Scale by percentage while keeping aspect ratio; 100% keeps the original size.

Reducing resolution can dramatically shrink files—often the most effective lever for oversized photos.

Compared with 100%: ~75% resolution saves ~30% size; ~50% saves ~65%; ~25% saves ~88% on average (other settings equal).

Output Format

Pick an output format—each has different strengths and use cases.

Auto Compress：With Auto selected, we apply:

JPG inputs → JPG compression
PNG inputs → PNG (lossy) compression
WebP inputs → WebP (lossy) compression
AVIF inputs → AVIF (lossy) compression
HEIC inputs → converted to JPG

Format details below—you can also choose a specific format manually.

JPG：Most popular; no transparency. vs uncompressed PNG, often ~90% smaller. At quality 75, loss is usually hard to notice. Best default when you do not need alpha.

PNG (Lossy)：Transparency with slight loss; ~70% smaller than uncompressed PNG on average. Prefer JPG if you do not need transparency; prefer WebP (lossy) if PNG is not required.

PNG (Lossless)：Transparency without loss; ~20% smaller than uncompressed PNG. WebP (lossless) is often a better pick when PNG is not mandatory.

WebP (Lossy)：Transparency with slight loss; ~90% smaller vs uncompressed PNG—strong alternative to lossy PNG. Some older clients lack WebP support.

WebP (Lossless)：Lossless transparency; ~50% smaller vs uncompressed PNG. Older devices may not support WebP.

AVIF (Lossy)：Higher compression than WebP; ~94% smaller vs uncompressed PNG on average. Compatibility is still evolving—best when you know targets support AVIF.

AVIF (Lossless)：Lossless transparency but savings vs uncompressed PNG can be modest or negative. PNG/WebP lossless are often simpler choices.
