Frequently Asked Questions
What image formats can I resize?
JPG, PNG, WEBP, BMP, GIF, and TIFF.
What ways can I resize an image?
By exact pixel dimensions, by a percentage of the original size (1–500%), or by picking a trending preset — Instagram, YouTube, Facebook, LinkedIn, Full HD, 4K, and more.
Will resizing make my image blurry?
Downscaling uses LANCZOS resampling, a high-quality filter that keeps edges sharp. Upscaling an image beyond its original size will always look softer than the original, since new pixel detail has to be estimated — that's true of any resizer, not just CurePDF's.
Can I stop an image from being upscaled by accident?
Yes. The "prevent upscaling" option scales your target size back down proportionally if it would otherwise exceed the original image's dimensions.
Does resizing change my image's format?
Usually not. JPEG and WEBP images keep their format, and images with transparency are kept as PNG. Legacy formats like BMP, GIF, and TIFF are converted to JPEG.
Is it free, and is there a size limit?
Yes, it's completely free with no sign-up required. Size limits depend on your plan tier — see the tool page for the current limit on your account.
