Does cropping a PNG reduce quality?

No. PNG cropping is bit-identical: the pixels you keep are exactly the same pixels from the source — no recompression, no resampling, no quality loss. The output PNG is just a smaller image with the unwanted region removed.

Will transparency be preserved?

Yes. PNG's alpha channel is preserved during cropping. Logos, icons, and graphics with transparent backgrounds stay transparent in the output. This is the main practical advantage of cropping a PNG (vs converting to JPG and cropping) — JPG would flatten transparency to white.

Can I crop to exact pixel dimensions?

Yes. Enter precise X, Y, width, and height. Useful when a CMS template, ad slot, or app icon set requires specific dimensions (1080 × 1080 for Instagram, 512 × 512 for app icons, etc.). Pixel mode is also the safest for assets that need to align exactly to a UI grid.

Can I batch crop many PNGs with the same crop region?

Yes — drop in multiple files and apply the same X / Y / width / height to all of them. Useful for cropping a series of screenshots taken at the same window size, framing a batch of product photos, or trimming whitespace off a folder of icons. Each file processes in parallel and downloads individually or as a ZIP.

How is cropping different from resizing?

Cropping removes pixels — output has fewer pixels than input, but each kept pixel is unchanged. Resizing changes the pixel count by interpolation — every pixel is recomputed. Cropping preserves quality exactly; resizing introduces (usually invisible) softness. To do both, crop first, then resize the result.

Will the file size be smaller after cropping?

Yes — proportionally to how much you removed. A 1920 × 1080 PNG cropped to 800 × 600 keeps roughly 23% of the pixel area, so the file size shrinks roughly 70-80% (depending on how much detail was in the kept region). Cropping is the single most effective lossless way to shrink a PNG.

Can I crop to a circular or rounded shape?

Standard PNG crop is rectangular. For rounded-corner or circular masks, you'll need an image editor (Photoshop, GIMP, Photopea) or a CSS clip-path on the rendered web page. The crop tool here outputs rectangular crops only — but you can crop tightly to a square first, then apply a rounded mask in your editor.
