Who Needs This Tool?
Students & Applicants
Online application portals (university admissions, government forms) often have strict file size limits like 'under 50KB' or 'maximum 2MB'.
- • Compress ID photos and scanned documents instantly.
- • Use 'Target Size' mode to hit the exact 50KB limit.
Web Developers
Large images kill page load speed and hurt SEO ('Core Web Vitals'). Compressing assets is the #1 way to speed up a website.
- • Convert heavy PNG heros to efficient WebP.
- • Reduce LCP (Largest Contentful Paint) times drastically.
Content Creators
Social media platforms compress visuals aggressively, often ruining quality. Pre-compressing gives you control over the final look.
- • Optimize YouTube thumbnails to under 2MB.
- • Prepare clearer images for blog posts and newsletters.
Professionals
Email attachments often bounce if they exceed 25MB. Compressing reports and presentation slides ensures your emails get delivered.
- • Shrink scanned contracts and invoices.
- • Share high-quality portfolios without the bulk.
Advantages of Client-Side Compression
Traditional tools force you to upload your potentially sensitive files to unknown servers. They might store copies, or you might hit slow upload speeds on poor connections.
Our tool solves this by using WebAssembly Technology. This means the actual 'engine' that compresses your images is downloaded once and runs entirely inside your browser.
- Zero Server Uploads (100% Privacy)
- Instant Processing (No Lag)
- Works Offline after loading
🔒 Privacy & Security Promise
We believe your photos belong to you. Because our technology processes files locally:
💡 Educational Note: Why WebP?
You might notice we recommend WebP as an output format. WebP is a modern image format developed by Google specifically for the web. It provides superior lossless and lossy compression for images on the web.
- Smaller Files: WebP images are typically 25-34% smaller than comparable JPEG images.
- Transparency: Unlike JPEGs, WebP supports transparent backgrounds (like PNGs) but with much smaller file sizes.
- SEO Boost: Google explicitly rewards websites that use 'Next-Gen' formats like WebP with better page speed scores.

Frequently Asked Questions
Is this image compressor completely free to use?
Yes, this tool is 100% free. We do not charge for premium features, there are no credits to buy, and we do not watermark your images.
Is it safe to upload my personal photos?
Absolutely. In fact, you aren't 'uploading' them in the traditional sense. Our tool processes the images locally in your browser using JS/WebAssembly. No server ever sees your files.
How do I compress an image to a specific size (e.g., 50KB)?
Use the 'Target Size' toggle button in the settings panel. Enter your desired size (e.g., 50), and our algorithm will automatically adjust the quality to try and meet that target.
Does compressing an image reduce its quality?
Technically yes, but visually often no. We use 'smart lossy' compression which removes data the human eye struggles to see. At 80% quality, the file size drops dramatically but the image looks nearly identical.
What formats can I convert and compress?
You can upload JPG, PNG, or WebP files. You can choose to output them in their original format, or convert them to WebP for even better savings.
Can I use this on my mobile phone?
Yes! Because it works in the browser, this tool runs perfectly on iPhone (iOS) and Android devices without needing to install an app.
