How to Compress Images Online

Upload Your Images

Drag and drop PNG, JPG, or WebP images into the upload area. Batch upload is supported — add as many files as you need, up to 50 MB each.

Adjust Quality & Format

Use the quality slider to balance file size and visual fidelity. Optionally convert formats (e.g. PNG to WebP) or set max dimensions to resize during compression.

Compare & Download

Use the before/after slider to visually compare originals and compressed versions. Download individually or grab everything as a ZIP.

Features

Before / After Comparison

Drag the slider to visually compare your original and compressed images side by side. See exactly what you're trading for smaller file sizes.

Batch Compression

Upload and compress dozens of images at once. Images are processed sequentially to keep your browser responsive and memory usage low.

Format Conversion

Convert between PNG, JPEG, and WebP during compression. WebP typically delivers 25-35% smaller files than JPEG at the same visual quality.

Smart Resizing

Set optional maximum width and height constraints. Images larger than the limits are proportionally scaled down; smaller images are left untouched.

ZIP Download

Compressed a whole batch? Download every result as a single ZIP archive with one click — no need to save files one by one.

100% Client-Side

All processing happens in your browser via the Canvas API. Your images are never uploaded anywhere — complete privacy guaranteed.

Why Compress Images?

Page speed matters. Images typically account for 50-70% of a web page's total weight. Compressing them is the single most impactful optimization you can make for faster load times, better Core Web Vitals scores, and higher search rankings.

Modern lossy compression algorithms can reduce JPEG and WebP file sizes by 60-90% with virtually no perceptible loss in quality. The key is finding the right quality threshold for your content — photographs tolerate aggressive compression well, while text screenshots and pixel art need gentler settings.

Our compressor uses the browser's native Canvas API for encoding, which means it leverages your device's hardware-accelerated image processing. The result is fast compression without installing any software, and complete privacy since your images never leave your machine.

Frequently Asked Questions

How does the image compressor work?

The compressor uses the HTML Canvas API built into your browser. It decodes each image, optionally resizes it, then re-encodes it at your chosen quality level. Lower quality values produce smaller files with slightly reduced visual fidelity. All processing runs locally — your images are never uploaded to a server.

Is this image compressor free?

Yes, completely free with no limits. There is no signup, no watermarks, no file count restrictions, and no daily caps. Compress as many images as you need, as often as you want.

What image formats are supported?

The tool accepts PNG, JPG/JPEG, and WebP images up to 50 MB each. You can also convert between formats during compression — for example, compress a PNG as WebP for even smaller file sizes.

Will I lose image quality?

At the default 75% quality setting, the difference is virtually imperceptible for photographs. For pixel-perfect graphics or screenshots, try 85-95% quality. The before/after slider lets you compare results visually before downloading.

Can I compress multiple images at once?

Yes. Drop or select as many images as you like — they will be compressed sequentially to keep memory usage low. Once all images are processed, you can download them individually or as a single ZIP archive.

Are my images safe?

Absolutely. Every step — decoding, resizing, re-encoding — happens inside your browser using the Canvas API. No image data is ever sent over the network. Close the tab and the data is gone.
