Frequently Asked Questions
How do I resize an image to exactly 3000x3000 pixels?
Upload your image, click the '3000 × 3000' preset button, then click Resize. The tool draws your image onto a 3000×3000 canvas and exports it as JPG or PNG. If 'Keep aspect ratio' is checked, it fits your image within 3000×3000; uncheck it to stretch to exactly those dimensions.
How do I convert an image to 1000x1000?
Select the '1000 × 1000' preset after uploading, or type 1000 into both the Width and Height fields. Click Resize and download the result. This is the standard size for many product images, social media profile pictures, and print-on-demand services.
Why do print services require images at 3000x3000 pixels?
At 300 DPI (dots per inch), a 3000×3000 pixel image prints as a 10×10 inch image — the standard size for fine art prints, photo books, and canvas prints. Many print-on-demand platforms like Printful, Printify, and Redbubble require this resolution.
What is the best image size for Instagram?
Instagram displays square images at 1080×1080 pixels, landscape at 1080×566, and portrait at 1080×1350. For maximum quality, upload at exactly 1080×1080 for square posts. This tool lets you resize to any of these dimensions before uploading.
Does resizing up (upscaling) reduce quality?
Yes. Enlarging an image beyond its original pixel count adds pixels by interpolation, which makes the image look softer or blurry. For best results, only downscale (reduce dimensions). If you need a larger image, consider using an AI upscaling tool.
Is my image uploaded to a server?
No. All resizing happens locally in your browser using the HTML Canvas API. Your photo never leaves your device.
