Frequently Asked Questions
Does resizing an image reduce its quality?
Making an image smaller (downscaling) generally keeps it sharp since pixels are being removed cleanly. Making it larger (upscaling) by a big margin can introduce blur because new pixels must be interpolated — for large upscales, our dedicated Upscale tool with Lanczos interpolation gives better results.
What's the difference between resizing and cropping?
Resizing changes the overall dimensions of an image while keeping all of its content, just scaled up or down. Cropping removes part of the image to change its dimensions. Use our Crop tool if you want to cut out a specific area instead.
Is there a file size or dimension limit?
No hard limit is enforced by the tool itself — it runs entirely in your browser using the Canvas API, so the practical limit depends on your device's available memory. Most photos and graphics resize instantly.
Is my image uploaded to a server?
No. Resizing happens 100% locally in your browser using JavaScript and the Canvas API. Your image is never uploaded anywhere, which keeps private photos private.
Can I resize an image to an exact pixel size for a website or social media?
Yes — type the exact width and height you need, or use one of the presets. For platform-specific sizes (Instagram, YouTube, Twitter, etc.) the Social Media Resizer tool has ready-made presets for each platform.
Can I resize several images at once?
Yes. Select or drop multiple images and the same settings are applied to all of them. You download the results as one ZIP file. Everything is processed in your browser.
How do I resize an image to a specific file size in KB?
Enter a maximum file size in the KB box and choose JPG or WebP. The tool finds the highest quality that stays under that size. If it cannot reach the target, reduce the dimensions as well. PNG is lossless, so a KB limit does not apply to it.
How do I resize an image in inches or centimeters?
Switch the unit to Inches or cm and set the DPI (300 is common for print). The tool converts the size to pixels using that DPI, for example 2 inches at 300 DPI is 600 pixels.
Which output format should I choose?
Use JPG for photos, PNG for graphics, logos and screenshots that need sharp edges or transparency, and WebP for smaller files on the web. See our WebP vs PNG vs JPG guide for details.
