Frequently Asked Questions
- Does the image resizer upload my photos to a server?
- No. The image resizer runs entirely in your browser using the HTML5 Canvas API. Your images are never uploaded, transmitted, or stored on any server. Everything stays on your device.
- What image formats can I resize and export?
- You can drop any image your browser can decode (PNG, JPG, WebP, GIF, BMP). For output, you can choose between JPEG (smaller files), PNG (lossless quality), or WebP (best modern compression). Quality is adjustable for JPEG and WebP.
- How do I resize an image for social media?
- Select the 'Social media preset' mode and choose from 12 one-click presets including TikTok (1080x1920), Instagram Square (1080x1080), YouTube Thumbnail (1280x720), Twitter/X Post (1600x900), and more. The tool instantly resizes your image to the exact platform dimensions.
- Can I resize multiple images at once?
- This tool is designed for single-image precision resizing with live preview. For batch processing of many images at once, use our Bulk Image Optimizer which supports converting hundreds of images with a single ZIP download.
- Is the image resizer free? Are there file size limits?
- The tool is 100% free with no file size limits, no watermarks, and no sign-up required. Since processing happens entirely in your browser, the only constraint is your device's available memory.
