What Is Image Compressor Tool?

The tool supports all major image formats including JPEG, PNG and WEBP. You can process up to 50 images simultaneously (each under 20MB), making it ideal for photographers, web designers, social media managers and anyone who needs to optimize images for websites, emails or storage.

FAQs (Frequently Asked Questions)

What is the maximum number of images I can compress at once?

You can process up to 50 images simultaneously in one batch. Each file must be under20MB in size. The tool is optimized for bulk processing of web-optimized images rather than extremely high-resolution professional photography files.

Will compressed images lose quality?

Yes, but you control how much. Lower compression levels (near 100%) preserve more quality but result in larger files. Higher compression (near 0%) creates smaller files but may show artifacts. We recommend starting at 70% and adjusting based on your needs. The tool provides a good balance between quality and file size reduction.

What image formats does the compressor support?

The tool accepts all common image formats including JPEG, PNG, WEBP, GIF, BMP and TIFF. For output, you can choose to keep the original format or convert to JPG (best for photos), PNG (best for graphics with transparency) or WEBP (modern format with excellent compression).

How does browser-based compression work?

Unlike many online tools, our compressor processes images entirely in your browser using JavaScript. This means:

Your images never leave your computer
Faster processing with no upload/download delays
Complete privacy - we never see your files
Works even without internet connection after loading the page

Can I compress images without changing their dimensions?

Yes! The compressor only reduces file size through quality optimization and format conversion. It doesn't resize or change the pixel dimensions of your images unless you specifically choose to do so through additional editing tools.

Is there any watermark added to compressed images?

No watermarks are added to your compressed images. You retain full ownership and rights to all files processed through our tool. The service is completely free with no hidden restrictions or branding added to your output files.
