FAQ

How does the image resizer work?
It uses the HTML5 Canvas API to scale your image to the exact dimensions you specify. All processing happens in your browser — no server uploads.
Can I maintain the aspect ratio?
Yes! The lock icon between width and height keeps the aspect ratio locked by default. Click it to unlock if you need custom proportions.
What formats are supported?
JPEG, PNG, and WebP images. You can also choose a different output format — for example, upload a JPEG and download as WebP for smaller file size.
Can I resize multiple images at once?
Yes. Select multiple files in the file picker or drag and drop a batch. All images will be resized to the same target dimensions and can be downloaded individually.
What are the social media presets?
One-click presets for Instagram Post (1080x1080), Instagram Story (1080x1920), Facebook Cover (820x312), Twitter/X Header (1500x500), YouTube Thumbnail (1280x720), and LinkedIn Banner (1584x396).
What is the maximum size?
There is no limit — but very large images may be slow on older devices since processing happens in your browser.
Is my image data private?
Yes. Your images never leave your device. Everything is processed locally using the Canvas API.
Does resizing reduce image quality?
Enlarging always reduces sharpness because the browser interpolates new pixels. Downscaling preserves quality well. For AI-powered enlargement that adds real detail, try our <a href="/ai/image/upscaler">AI Image Upscaler</a>.
Can I resize images on my phone?
Yes. The tool works in any modern mobile browser. Drag-to-resize on the preview and social media presets work with touch input. Large batch operations may be slower on older devices.
How does this compare to Photoshop or Canva?
Unlike Photoshop, there is nothing to install and no subscription. Unlike Canva, your images are never uploaded to a server. We support batch resize, exact pixel input, percentage scaling, and social media presets — all free and instant.
What happens to EXIF metadata when I resize?
Canvas-based resizing strips EXIF data (camera info, GPS, orientation). This is actually a privacy benefit. If you need to keep metadata, use dedicated desktop software.
Can I resize and compress at the same time?
Resizing to smaller dimensions naturally reduces file size. For further compression, run the result through our <a href="/ai/image/compress">Image Compressor</a> or choose WebP output format for 25-35% smaller files.
What is the maximum dimension I can set?
The tool allows up to 10,000 pixels per side. Very large outputs may exceed your browser's canvas memory limit (16 megapixels on iOS Safari). A warning will appear if the output is capped.
