How to Crop Images Online: Exact Dimensions, Rotate, and Flip

Profile photos demand squares, screenshots need their edges trimmed, and sideways phone photos need straightening before any of that. imgKonvert's crop tool covers all three jobs, crop, rotate, and flip, in one editor that exports PNG. This guide covers the workflow that avoids the classic mistake: losing your selection halfway through.

What the Crop Editor Does

The editor works on one image at a time. You select a rectangular area by dragging on the preview or by typing exact X, Y, width, and height values, then download the result as a PNG. Rotate and flip controls sit above the crop fields for fixing orientation first. Dedicated pages focus the editor for each job: crop an image, rotate an image, and flip an image.

How to Crop an Image

1. Upload and preview

Open the crop tool and select an image. Wait for the crop preview to appear before doing anything else.

2. Fix orientation first

If the photo is sideways or mirrored, use rotate or flip now. This order matters: rotating or flipping clears the crop selection, so orientation always comes before framing.

3. Select the area

Drag a selection on the preview when framing matters most, or type exact pixel values when a platform demands specific dimensions. The output readout shows the resulting size before you download.

4. Download the PNG

Check the output dimensions, then download. The result is always PNG. If you need JPG or WebP, convert it afterwards.

Rotate and Flip Without Losing Work

Rotate turns the image in 90° steps. Two clicks make 180°. Small tilt corrections are not possible, so fix crooked horizons elsewhere.
Flip mirrors horizontally or vertically. When text or a logo reads backwards, you need a flip, not another turn.
Reset restores the full image area at any time, which is also handy for starting a second crop from the same upload.

Because every one of these clears the selection, the reliable order is always the same: orient, then select, then download.

Practical Use Cases

Profile photos: cut headshots to squares without losing the subject.
Screenshots: trim browser chrome and distracting edges before sharing in tickets and docs.
Receipts: extract the receipt from a larger photo for expense records.
Scanned documents: rotate upside-down scans upright, then crop to the page.

Common Mistakes

Cropping before rotating, which wipes the selection you just made.
Typing an area larger than the photo, which the fields cap at the image edges.
Expecting the crop to change formats. For exact dimensions plus a different format, crop first and convert second. Oversized sources can also be resized first.

Conclusion

Orient first, select second, download third, and the crop editor never surprises you. Start on the crop hub or jump to the focused page for your job: crop, rotate, or flip.
