Frequently Asked Questions
Common questions about resizing images, aspect ratios, and format conversion.
How does Pinatool preserve image sharpness during downscaling?
Pinatool uses high-quality smooth scaling so that shrinking high-resolution photos down to smaller web graphics or thumbnails keeps edges crisp and avoids jagged artifacts.
Can I resize images by percentage or scale factor?
Yes. You can switch between exact pixel sizing (e.g. 1920 × 1080) and percentage scaling (e.g. 50%, 75%, 200%). Quick presets let you halve, double, or scale your picture with a single click.
What is the "Do not enlarge" protection?
When enabled, this protection caps the target dimensions to the original image dimensions. It prevents accidental upscaling which can cause blurriness and pixelation on small photos or icons.
Are my photos uploaded to any remote server or cloud service?
No. All resizing and format conversion runs completely within your web browser. Your photos, screenshots, and graphics never leave your computer.
Can I convert image formats during resize?
Yes. You can preserve the original format or convert your output to modern WebP, lossless PNG (preserving transparency), or universal JPEG with custom compression quality.
