Frequently Asked Questions
How do I resize an image for Instagram?
Use the Social Pack tab — select Instagram presets and click Download ZIP to get all sizes at once: square (1080×1080), portrait (1080×1350), and story (1080×1920).
Can I crop multiple images at once?
Use the Batch tab to resize up to 20 images to the same dimensions and download them all as a ZIP archive. Crop is per-image by design.
Does quickr upload my images?
No. All processing happens in your browser using the Canvas API. Your files never leave your device — no server, no account required.
What image formats are supported?
JPEG, PNG, and WebP as input and output. HEIC, AVIF, BMP, GIF, and TIFF are not supported — you'll see a clear error message if you try to load them.
How do I lock the aspect ratio when resizing?
Click the lock icon between the width and height inputs in the Resize tab. When locked, changing one dimension automatically updates the other to maintain the original proportions.
