Free online image compressor
This free image compressor shrinks JPG, PNG, WebP, GIF and SVG images online without losing visible quality. Everything happens directly in your browser — your photos and graphics are never uploaded to a server, so compression is fast, private, and works even on a slow connection. Smaller images mean faster websites, quicker email attachments, and files that fit under upload limits — with no software to install and no watermark.
How to compress images
Three steps, zero uploads.
Upload images
Drag & drop or select your JPG, PNG, WebP, GIF or SVG files. Add as many as you like — they all stay on your device.
Choose quality or target size
Pick a quality level, switch the output format, or enter a target file size like 200 KB and let the tool do the work.
Download compressed files
Save each image, or grab them all at once as a single ZIP. No sign-up, no waiting, no watermark.

Frequently asked questions
Is this image compressor free?
Yes — it's completely free with no sign-up, no limit on how many images you compress, and no watermark on your files.
Are my images uploaded?
No. All compression happens locally in your browser using the Canvas API and Web Workers. Your images never leave your device — nothing is uploaded, stored, or sent anywhere.
Can I compress an image to 200KB?
Yes. Turn on Target size mode and enter a value like 200 KB. The tool runs several compression passes to land as close to your target as it can while keeping the best possible quality.
Does compression reduce quality?
Lossy formats (JPG, WebP, AVIF) trade a little quality for a much smaller file. Around 70–85% quality the difference is usually invisible. You can preview before and after with a slider and fine-tune the quality per image.
Can I compress multiple images at once?
Absolutely. Drop or select many images and they compress in batch, then download them individually or all together as one ZIP file.
What is the best format for websites?
WebP is the best all-round choice — broadly supported and noticeably smaller than JPG or PNG at the same quality. AVIF is even smaller where the browser supports it. You can convert JPG or PNG to WebP here in one step.
