Quick Answer: What is image compression?
Image compression reduces the file size of a digital image by removing redundant or less important data. Lossy compression (like JPEG) achieves smaller sizes by discarding subtle colour details that human eyes barely notice. Our tool uses intelligent lossy compression to hit exact KB targets while preserving visual quality.
Quick Answer: How do I compress a passport photo?
Passport and visa applications typically require photos between 10 KB and 50 KB. Upload your passport photo to our tool, select the size required by your application (e.g., 20 KB for most Indian portals), and download. Our browser-based compression ensures your photo stays private.
Frequently Asked Questions
Is CompressImg.in really free?
Yes, completely free. There are no hidden charges, no premium plans, and no feature gates. Every tool on the site is free to use as often as you like.
Are my images safe? Do you store them?
Your images are never uploaded to our servers. All compression happens inside your browser using the HTML5 Canvas API. We have no access to your files, and they are deleted from memory as soon as you leave the page.
What is the maximum image size I can compress?
There is no enforced file size limit. However, very large images (50 MB+) may take a few extra seconds to process depending on your device's processing power. Most modern smartphones and laptops handle 10–20 MB originals in under 3 seconds.
Can I compress multiple images at once?
Yes — use our Bulk Image Compressor tool for batch processing. It allows you to upload and compress multiple images simultaneously and download them all at once.
Does compression reduce image dimensions?
For very small targets (under 20 KB), the tool may reduce the pixel dimensions as well as quality to achieve the target. For most targets above 20 KB, the original dimensions are preserved and only JPEG quality is adjusted.
How do I reduce image size to 100KB?
Upload your image to our compressor, select 100 KB as your target, and click compress. The tool automatically adjusts quality to hit exactly 100 KB. Download the result instantly.
What is the best image size for online forms?
Most Indian government and exam portals require photos between 10 KB and 50 KB. Signatures are typically 4–20 KB. Check the specific form requirements and use our dedicated size tool.
