Learn how to shrink your JPEG, PNG, and WebP assets to exact sizes (like 50KB or 20KB) with zero quality loss.
Watch our short 5-minute video tutorial to see how we load files locally and apply target dimensions in real-time.
Image optimization is a vital skill in the digital age. Large raw photos from DSLR cameras or mobile devices can exceed 5MB. These files slow down websites, exhaust bandwidth, and violate size bounds on passport, exam, and visa portals.
Our platform uses your browser's local sandbox computational power to resize images. This guide details exactly how to compress your files in a few simple steps, avoid common visual errors, and comply with government specifications.
Start by dragging your JPEG, PNG, or WebP files onto the dash-bordered target box at the top of our homepage, or click "Select Images" to open your device's native file explorer. Since our software uses client-side javascript, the file loads instantly.
Once your files are parsed, input your desired file size in the "Size" field. For example, type "50" if you need a 50KB image. Our binary search fitting logic will automatically adjust the compression parameters to fit this boundary.
Click the "Compress Now" button. In milliseconds, your files are processed. An optimized card grid will appear. Click "Compare" to open the high-fidelity visual slider, enabling you to inspect original vs. compressed pixel quality side-by-side. Click "Download" to save the file.
Set a target size of **45KB** to ensure you stay safely under a 50KB portal limit. Keep the aspect ratio strictly 3.5:4.5. Always use high-contrast lighting for background passport checks.
For blog content, choose WebP output and keep hero graphics under **100KB**. Use JPEG for high-detail photos and PNG only if you require alpha channel transparency.
When sending multiple visual mockups, batch compress your layouts to **250KB** each. This maintains optimal clarity while preventing attachment size limit rejections.
For signature uploads, portals often enforce a strict **20KB** ceiling. Set your target to **18KB** and select PNG format to keep ink lines highly legible and prevent rejection.
Most government portals enforce a **50KB** maximum size for passport photos. Setting your target size to **40KB to 45KB** in our tool ensures compliance with the limit while keeping the photo clear enough to pass face recognition audits.
No, our browser-native Canvas script preserves standard RGB color spaces. However, high-density ICC profiles or heavy camera EXIF headers are stripped away during scale adjustments, which helps reduce file size significantly.
