Is my image safe when I crop it online?

Your image is read into your browser and processed with the Canvas API. It is never uploaded to any server, stored anywhere, or shared with a third party. You can verify this by watching your browser's network tab while you crop.

What Is an Online Image Cropper?

An online image cropper lets you select and keep part of a photo without installing anything. You choose either an aspect ratio — 1:1 for a square, 16:9 for widescreen — or exact pixel dimensions, then drag a frame over the area you want.

This tool runs entirely in your browser using the HTML5 Canvas API. The image is read from your device and never uploaded, so it is equally suitable for a holiday snap and a scanned document.

Social media size guide

Platform	Format	Ratio	Recommended size
Instagram feed	Square	1:1	1080 × 1080 px
Instagram portrait	Portrait	4:5	1080 × 1350 px
Stories / Reels / TikTok	Vertical	9:16	1080 × 1920 px
YouTube thumbnail	Widescreen	16:9	1280 × 720 px
Standard photography	Landscape	3:2	1200 × 800 px
X / Twitter header	Wide banner	3:1	1500 × 500 px — use Free mode and type the values

The five preset buttons cover the most common shapes in one click. For anything else — banners, print sizes, app icons — switch to Free and type the width and height you need.

How to Crop an Image to an Exact Size

Step 1 — Add your image. Drag it in or click Choose Image. There's no upload and no file size limit beyond your device's memory.
Step 2 — Pick a ratio. Choose a preset to lock the shape, or Free to drag any rectangle.
Step 3 — Type exact values if you need them. The Width and Height fields show the crop size in pixels of the original image. Type a value and the box resizes to match — anything larger than the source is capped so you never get blank padding.
Step 4 — Position the frame. Drag the box, or pull a corner handle to resize. On a phone, use your finger — the handles are sized for touch.
Step 5 — Choose a format and download. Auto keeps transparency by saving PNG when it finds any; otherwise it saves JPG. You can force either format.

About quality

The crop is taken from the original image at full resolution — nothing is scaled or resampled, so no detail is lost in the crop step itself. Saving is a separate matter: PNG is lossless and reproduces the cropped pixels exactly, while JPG is re-compressed at 95% quality, which is visually near-identical but not bit-for-bit identical. If you need an exact copy of the cropped region, choose PNG — bearing in mind it will usually be a larger file for a photograph.

Common Uses

Social media: reframe photos to each platform's shape using the presets.
Web layouts: extract hero images, product thumbnails or banner sections at exact pixel sizes.
Email templates: hit the precise dimensions a template expects so images render correctly.
Profile pictures: the 1:1 preset gives a perfect square for avatars and team pages.
Print preparation: crop to 3:2 or type print proportions before sending to a print service.
Documents and screenshots: trim away everything except the region that matters, without uploading a sensitive screenshot anywhere.

Frequently Asked Questions

How do I crop an image online?

Drop your image onto the area above, pick an aspect ratio preset (or Free), drag the crop box to frame your subject, resize with the corner handles, then click Apply & Download. It works with touch as well as a mouse, and all processing happens in your browser.

Can I crop to exact pixel dimensions?

Yes — type the width and height into the crop size fields and the box updates to match. Values larger than the source image are capped to what the image actually contains, so your result never has blank padding round the edges.

Does cropping reduce image quality?

The crop itself doesn't — the region is taken at full original resolution with no scaling. The saving step depends on format: PNG is lossless and reproduces the cropped pixels exactly; JPG is re-encoded at 95% quality, visually near-identical but technically lossy. Pick PNG if you need an exact copy.

What aspect ratios are available?

1:1 (square, avatars), 4:5 (Instagram portrait), 16:9 (YouTube, widescreen), 3:2 (standard photography) and 9:16 (Stories, Reels, TikTok), plus Free for any shape. For a specific banner size, use Free and type the values.

Will my transparent PNG stay transparent?

Yes. The tool scans the whole cropped region for transparency and saves PNG whenever it finds any, preserving the alpha channel. If you deliberately choose JPG, transparent areas are filled with white rather than turning black, since JPG has no alpha channel.

Does it work on a phone?

Yes. Dragging and resizing use pointer events, so touch, stylus and mouse all behave the same way, and the corner handles are sized for fingertips. The page won't scroll while you're dragging the crop box.

Is my image safe?

Your image is read into your browser and processed with the Canvas API. It's never uploaded, stored, or shared. Open your browser's network tab while cropping and you'll see no request carrying your file.
