Frequently Asked Questions

What image formats does the resizer support?▾

Input: JPG, PNG, WebP, GIF, BMP, TIFF, SVG. Output: PNG (lossless quality), JPG (adjustable compression), WebP (modern format with superior compression). All processing happens locally in your browser for maximum privacy.

How does image resizing affect quality?▾

We use advanced resampling algorithms: Lanczos (best for photos), Bicubic (balanced), and Nearest Neighbor (for pixel art). Quality loss is minimal when downscaling. For upscaling, we use smart interpolation to maintain sharpness while avoiding pixelation.

What are the maximum image dimensions and file size?▾

Maximum dimensions: 10,000×10,000 pixels. Maximum file size: 50MB per image. For larger files, we recommend using our Image Compressor tool first. All processing is client-side - no files are uploaded to our servers.

Can I resize multiple images at once?▾

Yes! Our batch processing feature allows you to upload multiple images and resize them all with the same settings. You can download individual files or a ZIP archive containing all resized images.

What are the recommended dimensions for social media platforms?▾

We include presets for: Instagram (1080×1080, 1080×1350), Facebook (1200×630), Twitter (1500×500), LinkedIn (1200×627), Pinterest (1000×1500), and YouTube (1280×720). One-click optimization for each platform.

How does the aspect ratio preservation work?▾

When "Maintain aspect ratio" is enabled, changing one dimension automatically calculates the other to preserve the original proportions. This prevents distortion and ensures images look natural across different display sizes.
