❓ Frequently Asked Questions

Everything you need to know about image resizing

Are my uploaded images secure and private?↓

Yes, 100%! Unlike other websites, MyImgResizer.com does not upload your files to any remote server. All resizing, format conversions, and compressions are calculated locally in your browser's memory using HTML5 Canvas & WebAssembly APIs. Your personal photos never leave your device.

How does the Target File Size solver work?↓

If an online application requires an image to be strictly below a specific size (like 50 KB or 200 KB), you simply enter that value in the Target Size tab. Our engine automatically performs a high-speed binary search across compression quality and dimension thresholds to find the highest-clarity result that stays underneath your byte limit.

What is the difference between JPG, PNG, WebP, and AVIF?↓

JPG (JPEG): Best for general photos with high compression ratios.
PNG: Lossless quality, best for logos, text, and graphics with transparent backgrounds.
WebP: Google's modern format offering 30% smaller sizes than JPG at equal visual quality.
AVIF: Next-gen format with superior compression efficiency for web performance.

What DPI should I select for printing or passport photos?↓

Use 300 DPI for physical printing, official documents, passport 2x2" photos, and brochures to guarantee razor-sharp print quality. Use 72 DPI for standard web images and social media posts.

Can I resize multiple images at once for free?↓

Yes! You can drag and drop dozens of photos at once. You can customize them or batch apply your settings, and download all resized images bundled into a single ZIP file with zero fees and no subscriptions.
