Frequently Asked Questions
We answer your questions about privacy, features, and limits.
Can I enter an exact width and height?
Yes. Enter the target width and height in pixels. The controls show the px unit so the output dimensions are clear.
What does Proportional do?
When Proportional is enabled, changing one dimension updates the other to preserve the original aspect ratio and avoid stretching.
What presets are available?
Social media: Instagram square (1080×1080) and portrait 4:5 (1080×1350), stories, Reels, and TikTok (1080×1920), shared links (1200×630), X post (1600×900) and header (1500×500), LinkedIn banner (1584×396), Pinterest pin (1000×1500), and profile photo (400×400). Video: YouTube thumbnail (1280×720) and banner (2560×1440). Web: Full HD banner (1920×1080), wide banner (1920×600), blog image (1200×800), and app or site icon (512×512).
Will a preset crop my image?
A preset gives the exact size the platform asks for, so if your image has a different shape, the edges are cropped and the rest stays centered. The preview darkens the part that is removed. Choose “Fit without cropping” to keep the whole image instead.
Can I resize several images in one batch?
Yes. Add multiple images and apply a maximum pixel frame to the batch. The tool keeps each image proportional rather than forcing one crop.
Can I resize a PDF?
Yes. The pixel dimensions set the resolution of each page image, each page keeps its original paper size, and the result is still a PDF.
Can I resize by percentage?
No. The current controls use pixel dimensions. This gives you a specific output size for profiles, posts, stories, banners, and web layouts.
How do I download resized results?
Download each completed image individually or download the batch as a ZIP file. Use Compress afterward if the resized files still need a smaller file size.
