Does cropping change the file format or the quality?

The format never changes — a JPG comes back a JPG, a PNG a PNG. The pixels you keep are the original pixels at their original size, because cropping removes area rather than resampling it. JPG, WebP and HEIC are lossy formats and have to be encoded again to be saved, which is a small one-off cost; PNG, BMP, TIFF and GIF come back losslessly.

How do I crop to a square, or to 16:9?

Choose ‘A fixed aspect ratio’ and pick the one you want. The crop takes the largest area of that shape the image allows and centres it, so a 4000 by 3000 photo cropped to 1:1 gives you the middle 3000 by 3000. You can then drag the rectangle to move it, and it stays locked to the ratio while you do.

Can I type exact pixel measurements instead?

Yes, and they are on screen in every mode. Fill in a width and a height and leave the offsets empty to take that exact area from the middle; open Advanced options and set the offsets too if you want it from a particular corner. Any box left empty has a sensible meaning rather than being an error — an empty offset centres the crop, and an empty side runs to the edge.

What happens when I crop several images at once?

The area you select is measured against the first image and the same part of every other image is used. A rectangle over the middle third of the first photo takes the middle third of all of them, whatever size each one is. That is predictable, but it is not always what you want: if your images are different shapes, pick an aspect ratio instead and every one is cropped to that exact shape.

Will a photo from my phone come out sideways?

No. Phones rarely rotate the sensor data — they record ‘turn this 90 degrees when displaying it’ alongside the pixels. That rotation is applied before the crop area is measured, so the rectangle you drew over the upright photo is the rectangle that is taken, and the result is upright too.

Is transparency kept?

Yes. A transparent PNG or WebP comes back transparent, and the transparency is untouched — a crop copies pixels without compositing them onto anything. A JPG or an ordinary BMP has no transparency to begin with, so there is nothing to lose there; a GIF keeps its single transparent colour.

Can I crop and resize in one go?

Not in one job, deliberately. They are separate decisions with separate results — a crop changes which part of the picture you have, a resize changes how many pixels it is stored at — and combining them hides which one caused a change you did not expect. Crop here, then run the result through Resize Image, or the other way round.

Is this converter free?

Yes. Every conversion on ConvertNicely is free to use, with no account, no watermark on the result and no limit on how many files you convert.

What happens to my files?

Your uploaded file is deleted from our servers the moment the conversion finishes, whether it succeeded or failed. The converted result is deleted automatically one hour later, and you can delete it yourself at any time with the Delete button.

Is there a file size limit?

Files up to 50 MB are accepted for this conversion. Larger limits apply to paid plans in future, but the free limit is generous enough for the overwhelming majority of JPG conversions.

Do I need to install anything?

No. ConvertNicely runs entirely in your browser and on our servers, so there is nothing to download or install. It works the same on Windows, macOS, Linux, Android and iOS.

Does it work on a phone?

Yes. The whole site is built mobile-first, so you can upload from your camera roll or files app, convert, and download the result without leaving your browser.

Crop Images

Drag a rectangle over your picture, or pick a ratio like 1:1 or 16:9 and let the crop size itself. Nothing is scaled and nothing is resampled — the pixels you keep are the originals, at their original detail — and the file comes back in the format it went in as. Crop a batch at once, each to the same part of itself.

How to crop images

Step 1
1. Add your files
Drag up to 20 JPG, PNG, WebP, HEIC, BMP, TIFF or GIF files into the box, or choose them from your device. Each can be up to 50 MB.
Step 2
2. Choose the area to keep
Drag the frame on the preview, or type an exact Width and Height in pixels. Crop to (Any shape) can also hold the frame to a ratio such as 1:1 or 16:9. More settings are under Advanced options.
Step 3
3. Press Crop images
The work happens on our servers, and you can follow its progress.
Step 4
4. Download the result
Each file comes back in the format it went in; several come together in a ZIP. Your upload is already deleted, and the result is deleted after one hour.

Worth knowing

Cropping only removes; it never scales. A 1200 by 628 crop is 1200 by 628 pixels of the original, so asking for an area larger than the image is refused rather than stretched to fit. In a batch, the area you choose is measured on the first image and the same part of every other image is taken. That keeps mixed sizes predictable, but when the shapes differ a ratio is usually the better choice.

Why crop images?

Making a square or 16:9 version of a photo for a profile or a banner
Cutting a screenshot down to the part that matters before sharing it
Trimming distractions from the edges of a photograph
Getting a batch of product shots to a consistent shape for a listing
