Cropping itself does not reduce quality — but how you export can. Here is how to keep your cropped image as sharp as the original.
A crop is just a smaller window onto the same pixels. If your photo is 4000×3000 and you crop to the central 2000×1500, those 2000×1500 pixels are bit-for-bit the same as in the original — nothing is resampled. This tool cuts at full source resolution, so the area you keep is exactly as sharp as it was.
Choose PNG for lossless output and transparency — ideal for graphics, logos and screenshots. Choose WebP for a smaller lossless-ish file on the web. Use JPG only for photos where a small, high-quality file matters, and avoid re-saving the same JPG repeatedly. When you set an exact size, keep it at or below the source dimensions so you are never upscaling.
Open the highest-resolution version of the image in the cropper.
Frame your area. The kept pixels are untouched at source resolution.
If you set an exact size, keep it at or below the original dimensions.
Download as PNG (or WebP) to preserve detail and transparency.
For anything shown on a screen, only the pixel dimensions matter — DPI is a print setting that does not change how an image looks online. A 1000×1000 crop is exactly 1000×1000 pixels whether it is tagged 72 or 300 DPI. So when you crop for the web, ignore DPI and think in pixels: crop the area you want and keep it at or below the source size. For print, work back from the physical size and the printer’s DPI — a 4×6 inch print at 300 DPI needs 1200×1800 pixels — and crop from a high-resolution original so you are never enlarging.
As a quick rule: use PNG for graphics, logos, screenshots and anything with transparency or sharp edges — it is lossless. Use WebP when you want lossless-quality results at a smaller file size for the web. Use JPG only for photographs, and export it once at high quality rather than re-saving repeatedly. If a crop will be both printed and shown online, keep a lossless master (PNG or high-quality WebP) and make JPG copies only when a small file is specifically needed.

No. Cropping removes pixels outside the frame; the pixels you keep are unchanged. Quality only drops if you scale the crop down to fewer pixels or re-save as a lossy JPG at low quality.
Crop in a tool that cuts at full resolution and export as PNG (lossless) or high-quality JPG/WebP. The PNG cropper samples from the original pixels, so the kept area stays sharp.
PNG is lossless, so repeated edits never degrade it, and it keeps transparency. JPG is smaller but lossy; for photos a high-quality JPG is usually fine.
Usually because the crop was scaled up beyond the source resolution, or saved as a low-quality JPG. Crop from the largest original you have and export losslessly.
