Why use ZentaPDF Resize Image?
Frequently asked questions
Are my files uploaded to a server?
No. ZentaPDF processes your files inside your own browser using JavaScript. Nothing is uploaded, so nobody else can see your documents — not even us.
How do I resize without stretching the image?
Keep "Keep proportions" ticked. The image is scaled to fit inside the width and height you type, so its shape never changes. You can also fill in only the width or only the height.
Can I resize many images at once?
Yes. Add as many images as you like — they are all resized with the same settings and you can download them together in a ZIP file.
Will resizing make my image blurry?
Making an image smaller keeps it sharp. Making it bigger than the original cannot add detail, so "Don’t enlarge small images" is on by default.
Is it really free? Do you add a watermark?
Yes, it is completely free with no sign-up, no watermark and no daily limits. The site is supported by a few non-intrusive ads.
