Frequently Asked Questions

What's the maximum file size I can upload?

You can upload images up to the size shown on the upload box. For larger files, try compressing them first or use our Image Compressor tool.

Will resizing reduce my image quality?

Making images smaller generally maintains quality. Enlarging images beyond their original size may cause some pixelation, especially with significant upscaling.

How do I use the social media presets?

Click any platform button (like Facebook or Instagram), then select the specific image type from the dropdown (like "Post" or "Story"). The dimensions will be applied automatically.

What does the real-time size indicator show?

The indicator displays the current width and height in pixels of your crop selection. It updates instantly as you drag the crop handles, so you always know the exact dimensions before downloading.

Can I resize without cropping?

Yes! Simply don't adjust the crop box and use the percentage slider or custom size inputs to resize the entire image proportionally.

What's the difference between "Lock Aspect Ratio" and "Stretch to Fit"?

Lock Aspect Ratio keeps your image proportions intact (no distortion). Stretch to Fit forces the image to exactly match your width and height, which may cause stretching if the ratios don't match.
