Frequently Asked Questions
Can I resize an image to exact pixels?
Yes. Choose pixel resize, enter the target width and height, and keep aspect ratio enabled if you want proportional resizing.
Can I resize images for Instagram?
Yes. Use the social presets for common Instagram and social media sizes, or enter a custom pixel size.
Do you upload my files?
Image resizing happens locally in your browser, so your files stay on your device. No sign-up needed to download your resized images.
Can I increase image size?
Yes, you can enlarge images by pixels or percentage. Enlarging uses interpolation to add pixels rather than new detail, so very large increases can look softer or blurry.
Need to split resized images into posts or tiles?
After resizing, jump straight into Instagram grids, carousels, or custom image splits for final export.
