How to Compress an Image Online — Step by Step

Upload your image by clicking the area above, paste with Ctrl+V, or drag and drop. Select your target size — 20KB for signatures, 50KB for exam forms, 100KB for passports. The engine automatically compresses your image by reducing JPEG quality iteratively. If needed, dimensions are proportionally reduced until the target is met. Download your compressed image with one click — the filename includes the target size for easy identification.

Why Compress Images for Government Portals?

Indian government portals — SSC, UPSC, passport seva, income tax, IRCTC, banking — specify strict file size limits. Photos typically must be under 50KB or 100KB, and signatures must be under 20KB or 30KB. Uploading an oversized file causes form rejection. This tool compresses your image precisely to meet these limits without multiple rounds of manual trial and error.

Which Format Should I Choose?

JPG: Best for photographs — achieves small file sizes with minimal visible quality loss. Use for photos, ID scans, passport images. WEBP: 25–35% smaller than JPG at same quality — best choice for web use. Not accepted by some government portals, so check before using. PNG: Lossless format — cannot be compressed to very small sizes for photographs. Use PNG only for screenshots, logos, or images needing transparency.

Frequently Asked Questions

Is my image uploaded anywhere?
No. All processing is done in your browser using HTML5 Canvas API. Your image never leaves your device. No servers involved.
How does the compression algorithm work?
The engine starts at high quality (94%) and reduces the JPEG quality in steps of 5% until the output is at or below the target. If quality reaches 28% and the file is still too large, it proportionally reduces image dimensions by 12% and retries. This continues until the target is met or 55 attempts are exhausted.
Will the image quality be noticeably reduced?
It depends on the original image and target size. Compressing a 3MB photo to 100KB typically shows no visible quality difference. Compressing a 4MB photo to 20KB requires heavy compression — photos with complex detail may show artefacts. The quality grade (A+, A, B, C) shown in the tool tells you how aggressive the compression was.
Can I compress multiple images at once?
Yes — use the Batch Compress section below. Upload up to 20 images, set a target, and download all compressed images as a ZIP file with one click.
What is the maximum file size I can upload?
Up to 20MB per image. Larger images may take 2–3 seconds to compress depending on your device, which is normal.
