What this image cropper does and who it is for
Drop in a PNG, JPG or WEBP and the image opens in a workspace that shows its original dimensions and file size straight away. Pick the aspect ratio you need from labelled presets — square for an Instagram post or profile picture, 16:9 for a YouTube thumbnail or web banner, 4:5 for a feed photo, 9:16 for Reels, TikTok and Stories, 21:9 for an ultra-wide hero header, 3:2 for print and DSLR photography, and 4:3 for tablets and in-article media — or switch to Custom and drag the handles freely.
The crop box can be dragged around the image and resized from any of its eight handles. With a preset selected the ratio stays locked no matter which handle you pull, so the result is always exactly the shape the platform wants. Shortcuts let you fit the whole picture inside the frame, fill the frame edge to edge, or flip a preset between landscape and portrait. A reset button returns everything to the untouched original.
Before you download, the panel shows the exact output dimensions and an estimated file size. Export as JPG, PNG or WEBP, tune the quality for the lossy formats, and optionally cap the longest side in pixels so the file is small enough to attach or upload without an extra compression step.
It is built for the people who resize the same photo for four different places every week: marketing staff, property and financial advisers posting listings and updates, shop owners preparing product photos, and anyone maintaining a company profile across several platforms.

Frequently asked questions
Are my images uploaded to a server?
- No. The file is read by your own browser, the crop is composited locally, and the download comes straight back from your device. Close the tab and nothing remains anywhere.
Which aspect ratio should I use for each platform?
- Instagram posts and profile pictures use 1:1, feed and carousel photos look best at 4:5, Reels, TikTok and Shorts are 9:16, YouTube thumbnails and web banners are 16:9, blog and tablet media suit 4:3, DSLR and print photos are 3:2, and wide hero headers use 21:9. Each preset is labelled with its use so you do not have to memorise them.
Can I crop to a size that is not in the list?
- Yes. Choose Custom for completely freeform handles, or type your own width and height numbers to lock a ratio of your choosing, such as 5:7 for a print frame.
Does cropping reduce the quality of my photo?
- The crop itself takes pixels directly from the full-resolution original, so nothing is softened. Quality only changes if you lower the JPG or WEBP quality slider or cap the longest side, both of which are optional and shown before you download.
Does it work on a phone?
- Yes. The crop box responds to touch, so you can drag and resize it with a finger, and the download saves straight into your phone's photo or files area.
