Why it matters
File Size Matters More Than You Think
Every kilobyte you save compounds across every page load, every visitor, and every device on every network.
Pages load faster
Images are the single biggest cause of slow websites. Compressing them shaves seconds off your first contentful paint — and every second costs you visitors.
Cut storage costs
Whether you're uploading to a CDN, cloud storage, or serving from your own server — compressed images translate directly into lower bandwidth bills and faster delivery.
Better Core Web Vitals
Google's LCP (Largest Contentful Paint) is almost always an image. Compress it and you directly improve the score that decides whether Google promotes or buries your page.

Compressed at 80% quality — the default setting. Open both images side-by-side at full size and try to spot the difference.
Supported formats
Three Formats. One Tool.
PNG, JPEG, and WebP are processed natively in your browser — no plugins, no downloads.
Perfect for graphics & logos
PNG uses lossless compression — no pixel data is ever discarded. FileCrisp still reduces PNG file sizes by removing metadata and applying zlib-level optimizations, without changing a single pixel.
Best for
- Logos & icons
- Screenshots
- Illustrations
Ideal for photos & real-world images
JPEG's lossy algorithm delivers incredible compression ratios for photographic content. At 80% quality, file sizes drop 70–85% while staying visually identical to the human eye at any normal viewing size.
Best for
- Photos
- Product images
- Backgrounds
Google's modern format — the best of both
WebP beats both PNG and JPEG for most content, delivering smaller files at the same quality. It supports transparency (like PNG) and lossy compression (like JPEG). Supported by all major browsers since 2020.
Best for
- Web delivery
- PWAs & SPAs
- Next-gen assets
Quality guide
Finding Your Sweet Spot
The quality slider controls the trade-off between file size and visual fidelity. Here's what each range means in practice.
Thumbnails & Previews
Maximum compression. Visible artifacts at close inspection. Ideal for placeholder thumbnails, email previews, and icons where pixel-perfect quality isn't needed.
Web & Social
The sweet spot. Files shrink 70–85% with no visible difference to the human eye at any normal screen size. This is FileCrisp's default — and the right choice for nearly every use case.
Print & Archive
Near-lossless results. Still achieves 20–40% size reduction over the original. Use when images will be viewed at extreme zoom or printed at high DPI.
FileCrisp defaults to 80% quality — the point where most images lose 70–85% of their size with no visible difference to the human eye. You can always fine-tune the slider before compressing.
