Frequently Asked Questions
Can I resize to an exact pixel size?
Yes. Enter the exact width and height in pixels, or use percentage mode to scale by a fraction of the original size.
Is aspect ratio preserved by default?
Yes. Aspect ratio is locked by default. Uncheck the lock to set width and height independently.
What image formats are supported?
JPG, PNG, and WebP are supported for both input and output.
Are my images deleted after resizing?
Yes. All files are automatically deleted within 2 hours.
Does resizing also compress the image file size?
Resizing to smaller dimensions naturally reduces file size. For maximum compression without changing dimensions, use the Compress Image tool — it reduces file size by 40–80% while keeping the same width and height. Both tools are free, no signup needed.
Can I resize a PDF page size?
For PDF files, use the Compress PDF tool to reduce file size, or the Merge PDF / Split PDF tools to reorganize pages. Image resize only works with JPG, PNG, and WebP files.
