Frequently Asked Questions
What presets are available?
Instagram Post/Story, Facebook, Twitter, LinkedIn, YouTube Thumbnail, HD, Full HD, 4K, Favicon, and App Icon sizes.
Can I maintain the aspect ratio?
Yes, in Custom Size mode you can toggle 'Keep aspect ratio' to prevent distortion.
What about image quality?
Use the quality slider (10-100%) to balance file size and quality. Higher quality = larger files.
How many images can I resize at once?
No limit — processing happens in your browser, so speed depends on your device.
What format are the resized images?
JPEGs stay as JPEG, other formats become PNG. Use the Format Converter for specific formats.
Can I resize by percentage?
Yes. Set a percentage like 50% or 200% and the tool scales every image proportionally.
Does it work on mobile?
Yes. Resize photos from your camera roll. Pick a preset, adjust quality, and download.
Is there a file size limit?
No server limits. Very large images may be slower on older devices, but there's no cap.
