Standard JPEG does not support transparency. Transparent areas from your image will be filled with your chosen background color.
Cropping your image...
Slicing pixel coordinates and re-encoding locally in your browser memory.
Cropping isolates selected coordinates. Output file size decreases proportionally based on discarded area and encoding settings.
Aspect Ratios, Framing, and Pixel-Level Accuracy
Cropping isolates the desired visual focal point of a photograph while discarding unwanted outer margins. Understanding aspect ratios and coordinate mapping ensures crisp, professional results across digital channels.
Frequently Asked Questions
How do I crop an image to an exact square (1:1)?
Select the "1:1 Square" preset button above the cropper. The crop selection box will immediately lock into an equal width-to-height ratio, and resizing the handles will maintain a square framing.
Does cropping reduce the file size of my image?
Yes. Because cropping eliminates outer pixels and reduces overall pixel resolution, the resulting file size is almost always significantly smaller than the original image.
Can I type in exact crop width and height in pixels?
Yes! You can manually enter custom pixel dimensions in the Width and Height input fields, and the crop box will adjust automatically on the screen.
What happens to transparent backgrounds in PNG or WebP images?
If you keep "Same as input (Auto)" or choose PNG or WebP as the output format, transparent pixels are preserved intact. If you export to JPEG, transparent areas will be filled with a solid white background.
Can I move the crop box after setting its size?
Yes. Simply click and drag anywhere inside the crop box to reposition it over the exact subject or area you want to keep.
Are my images stored or analyzed on your servers?
Never. Free Image Reducer processes all images directly in your browser using HTML5 Canvas APIs. No images are uploaded to any server or cloud backend.
