Why Use Our Image Compressor?

Professional-Grade Compression

We use the same compression technology as Netflix, Google, and Apple. Six different algorithms ensure your images get the best possible compression.

Process Hundreds at Once

Other tools limit you to 20 files or make you wait between uploads. Drop your entire photo library if you want - we'll process everything and package it into a single ZIP.

Real-Time Preview

See exactly what you'll get before committing. Our live preview updates as you adjust settings, showing you the compressed result and file size savings instantly.

Modern Format Support

Convert to WebP or AVIF for even smaller files. These next-gen formats can cut your file sizes in half compared to traditional JPEG, and all modern browsers support them.

Key Features

100% Private

Your images never leave your device. All compression happens right in your browser using your computer's processor. We physically cannot see your files.

Lightning Fast

No upload wait times. Compression starts immediately and finishes in seconds. A 10MB photo compresses in about 2 seconds.

Truly Unlimited

No file limits, no daily caps, no watermarks, no registration required. Compress 1 image or 1,000 - it's completely free.

Precise File Size Control

Need an image under 500KB for email? Enter your exact target and watch us hit it. Our smart algorithm finds the perfect quality level.

Frequently Asked Questions

Is this really free? What's the catch?
Yes, 100% free with no catches. Since everything runs in your browser, we don't have server costs for processing your images. No premium tiers, no watermarks, no limits.
Are my images really private?
Absolutely. Your images never leave your computer - all processing happens locally in your browser. We don't see your files, we can't access them, and nothing is uploaded anywhere.
Will compression make my images look worse?
Lossless mode: no, identical pixels. Balanced mode: no visible difference (imperceptible details removed). Maximum mode: possible minor artifacts in smooth gradients. Use the preview slider to check before downloading.
Is there a limit on batch processing?
No artificial limits. Process as many images as your device memory allows. We've tested with 500+ images. All results package into a single ZIP for easy download.
What image formats do you support?
All common types: JPEG, PNG, WebP, GIF, BMP, TIFF, ICO, AVIF, and HEIC (iPhone photos). You can output as JPEG, PNG, WebP, or AVIF.
Which compression algorithm should I choose?
Start with Auto - it analyzes your image and picks the best method. MozJPEG for photos, OxiPNG for graphics with transparency, WebP for modern web, AVIF for maximum compression.
How does Target Size mode work?
Enter your maximum size (e.g., 500 KB). We run multiple compression passes, adjusting quality each time, until we find the highest quality that fits under your target. If the target is too aggressive, we'll show the smallest achievable size.
What about EXIF data and photo location?
By default, we strip all metadata (camera info, GPS coordinates, timestamps) for privacy. Photographers can enable 'Preserve Metadata' in Output Settings to keep EXIF, IPTC, and XMP data intact.

About Image Compression

Image compression reduces file sizes while maintaining visual quality. Smaller images load faster on websites, take up less storage, and are easier to share via email or messaging apps.

Lossless Compression

Reduces file size by 20-50% without changing a single pixel. Uses smart encoding techniques to store the same image data more efficiently. Perfect for logos, graphics, screenshots, or any image where pixel-perfect quality is essential.

Lossy Compression

Achieves 60-80% file size reduction by removing details that are invisible to human eyes. The images still look identical to most people - this is how photos on the web and social media work.

Modern Formats

WebP and AVIF are newer image formats that offer significantly better compression than traditional JPEG and PNG. WebP is 25-35% smaller with 95% browser support. AVIF can be 50% smaller with growing support.
