File Type

What type of file do you want to compress?

Use Case

What are you trying to achieve?

Recommended Algorithm

Brotli

Output format: HTTP Content-Encoding: br

Typical Reduction

65–85%

Why This Algorithm

Brotli achieves 15–25% better compression than GZIP for text content and is supported by all modern browsers. Enable it on your web server or CDN for maximum bandwidth savings.

Recommended Tool

HTTP Response Size Analyzer

Alternatives

GZIP— 60–80% reduction — universal fallback for all browsers

Zstandard— 70–88% reduction — best for high-traffic APIs (requires server support)

💡 Tips

Always include GZIP as a fallback for clients that do not support Brotli.

Add Vary: Accept-Encoding to ensure CDNs cache compressed and uncompressed versions separately.

Recommendations are based on typical use cases and industry best practices. Actual compression ratios vary by content complexity and specific file characteristics.

Common Use Cases for Compression Type Recommender

Web Server Configuration

Determine whether to enable GZIP or Brotli for each content type on your nginx or Apache server — the recommender tells you which algorithm gives the best savings for each file type.

API & SDK Development

Choose the right compression for API responses, OpenAPI specs, and SDK artifacts — the recommender distinguishes between web delivery (Brotli) and SDK generation (field removal) use cases.

DevOps & Infrastructure

Select the right compression for log archiving, backup pipelines, and artifact storage — the recommender covers GZIP, ZIP, TAR.GZ, and format-specific options for each scenario.

Mobile App Development

Find the best compression for mobile assets — fonts, images, and config files — with recommendations tailored to mobile upload limits and app bundle size constraints.

CDN & Storage Optimization

Identify which assets benefit most from compression before uploading to S3, CloudFront, or Cloudflare — the recommender flags already-compressed formats that waste CPU.

Learning & Onboarding

Quickly learn which compression algorithm is appropriate for a new file type or use case — the recommender explains why each algorithm is recommended with practical tips.

Understanding Compression Algorithm Selection

What is a Compression Type Recommender?

A compression type recommender analyzes your file type and intended use case to suggest the most appropriate compression algorithm, output format, and tool. Different file types and use cases call for very different approaches — GZIP for web delivery, ZIP for file sharing, WOFF2 for fonts, and format-specific codecs for images and video. Our free compression type recommender covers 25+ file types and 11 use cases with instant recommendations.

Select Your Use Case: Choose from 11 use cases — web delivery, file sharing, archiving, SDK generation, mobile upload, and more.
Get an Instant Recommendation: The recommender shows the best algorithm, typical reduction, why it was chosen, alternatives, warnings, and a direct link to the right tool.

Key Compression Algorithm Comparison

Brotli: Best for web delivery — 15–25% better than GZIP for text. Supported by all modern browsers. Use as primary with GZIP fallback.
GZIP: Universal — supported everywhere. 60–80% reduction for text. Best for archiving, server-side compression, and legacy compatibility.
ZIP (DEFLATE): Best for file sharing — natively supported on all operating systems. Good for bundling multiple files.
Format-specific codecs: JPEG, WebP, AVIF for images; WOFF2 for fonts; H.264/VP9 for video — always better than generic compression for these types.

When NOT to Compress

Some file types should not be compressed with generic algorithms because they are already compressed internally: JPEG, PNG (partially), WebP, AVIF, MP3, AAC, MP4, WebM, ZIP, GZIP, and WOFF2. Applying HTTP GZIP or Brotli to these formats wastes CPU on every request while achieving 0–5% additional reduction. The recommender flags these cases with a warning and suggests format-specific optimization instead.

Frequently Asked Questions About Compression Type Recommender

GZIP is the most universally supported HTTP compression algorithm — all browsers and servers support it. Brotli achieves 15–25% better compression than GZIP for text content and is supported by all modern browsers (Chrome, Firefox, Safari, Edge). For web delivery, use Brotli as primary with GZIP as fallback.

Some formats (JPEG, MP4, MP3, ZIP, WebP) are already compressed using their own internal codecs. Applying HTTP GZIP or Brotli on top adds almost nothing (0–5% reduction) while wasting CPU on every request. For these formats, reduce size at the source using format-specific tools.

Yes. The compression type recommender is 100% free with no signup, no subscription, and no limits. You can get as many recommendations as you need.

Use ZIP for sharing with Windows users — it is natively supported without additional software. Use GZIP for single-file compression on Linux/macOS servers. Use TAR.GZ to bundle multiple files while preserving directory structure. All three use DEFLATE compression internally.

Brotli is the best algorithm for web delivery — it achieves 15–25% better compression than GZIP for HTML, CSS, JavaScript, and JSON. Enable Brotli on your server with GZIP as a fallback. Always add Vary: Accept-Encoding to ensure CDNs cache both versions correctly.

No. Raster images (JPEG, PNG, WebP, AVIF) are already compressed using their own codecs — HTTP compression adds almost nothing. Instead, optimize images at the source: convert to WebP or AVIF for photos, use PNG lossless compression for screenshots, and reduce quality/resolution for large files.

For web delivery, convert fonts to WOFF2 — it uses Brotli compression internally and is 30–50% smaller than TTF. For archiving or sharing, GZIP compresses TTF/OTF files by 40–60%. Never serve raw TTF or OTF on the web — always use WOFF2.
