Quick start

How to crop an image in your browser

Drop an image, drag the rectangle to frame your subject, lock the aspect ratio, then export. Nothing uploads.

  1. Step 1
    Drop image

    Drag a PNG, JPG, WebP or AVIF file into the zone or click to pick.

  2. Step 2
    Frame the crop

    Pick an aspect ratio (1:1, 16:9, 9:16…) or stay on Free. Drag the rectangle and corners to position the crop. Type exact pixel values for precise crops.

  3. Step 3
    Export

    Pick PNG (lossless), JPEG (smaller) or WebP, set quality, then Crop & export. Download the result.

In-depth guide

Image crop — drag, snap to aspect, export

An image cropper that runs entirely in your browser. Drag a rectangle on the preview or type exact pixel values, lock to a common aspect ratio, and export as PNG / JPEG / WebP. Your image never leaves your device.

Common aspect ratios — pick the right one

  • 1:1 — Instagram square, profile picture, app icon.
  • 4:3 — classic point-and-shoot photos, iPad screen.
  • 3:4 — portrait photo, mobile-first hero image.
  • 16:9 — YouTube thumbnail, widescreen video frame, TV-format slide.
  • 9:16 — Instagram / TikTok reel, story, mobile vertical video.
  • 3:2 — DSLR full-frame and APS-C sensor native ratio.
  • 5:4 — Instagram portrait post, 8×10 print.
  • 21:9 — cinematic widescreen / ultrawide monitor wallpaper.

PNG vs JPEG vs WebP for the output

Three encoders cover most needs:

  • PNG — lossless, supports transparency. Use for screenshots, logos, anything with text, or when you need an alpha channel. File sizes are large.
  • JPEG — small lossy format, no alpha. Use for photos. Quality 80–90% is visually indistinguishable from the source for most viewers; below 70% you start to see blocking and color smearing.
  • WebP — modern lossy format with alpha support. ~25-35% smaller than JPEG at the same visual quality. Supported in all modern browsers; for compatibility with old software fall back to JPEG.

Practical tips

  • Match the destination platform's spec. Twitter banners are 1500×500 (3:1), LinkedIn covers 1584×396 (4:1), YouTube thumbnails 1280×720 (16:9). Crop to the exact pixel size to avoid platform-side recompression.
  • For avatar uploads, use 1:1. Most platforms display avatars as circles or rounded squares cropped from the center. Composing your subject at the center of a 1:1 crop guarantees the framing survives.
  • Keep a copy of the original. Crops are destructive — once exported, you can't recover the trimmed pixels.
  • EXIF / metadata are stripped. A Canvas re-encode does not preserve metadata. If you need to keep GPS, ICC profile or camera info, use a metadata-preserving tool like ExifTool.

When to use it vs alternatives

Use this tool for quick image cleanup, conversion, resizing, OCR, or export work where a browser-local workflow is enough. Use a dedicated editor when you need layered retouching, colour-managed print proofing, or scripted batch production.

Privacy and security

Browser-first by design. The tool page explains any exception before you use it.

Your selected images stay in your browser while the tool processes previews and downloads. Some tools may load site assets, scripts, or model files, but your input image bytes are not uploaded by EpitomeTool.

Frequently asked questions

Is my image uploaded anywhere?

No. Every byte of your image stays in your browser. The crop runs locally on a Canvas and we never see your photo.

Which file types are supported?

Anything the browser's native <img> tag can decode — PNG, JPG/JPEG, WebP, GIF (first frame), BMP, SVG and AVIF in modern browsers. For iPhone HEIC files, convert with our HEIC → JPG tool first.

Can I crop to a specific aspect ratio?

Yes — pick from 1:1 (square), 4:3 (classic photo), 3:4 (portrait), 16:9 (widescreen), 9:16 (story / reel), 3:2 (DSLR), 2:3, 5:4 (Instagram portrait) and 21:9 (ultrawide). Drag the rectangle freely or by handles; the ratio is locked.

Can I crop to an exact pixel rectangle?

Yes. The X, Y, width and height fields update live as you drag, and you can also type in exact pixel values for precise crops — useful for matching avatar requirements, social media banners, or print specs.

What output format and quality?

PNG (lossless, supports transparency), JPEG (smaller, no alpha — transparent areas become white) or WebP (smaller than JPEG with alpha support). For JPEG and WebP you can tune a 10–100% quality slider.

Does the cropper preserve image quality?

Yes — the crop is a direct pixel copy from the source. We don't downscale or upscale unless you explicitly choose to. For lossless crops use PNG output.

Are EXIF / metadata preserved?

No. The Canvas re-encode strips all metadata (EXIF, ICC profile, GPS, camera model). If you need to keep metadata, use a desktop tool like ExifTool. We have an EXIF viewer if you want to inspect metadata before stripping.

What's the maximum image size?

Modern browsers can handle 50+ megapixel images without issue. Phone-sized photos (12–48 MP) are well within reach. For 100 MP+ scientific or panorama images you may hit Canvas size limits (~16 384 × 16 384 in Chrome / Firefox).
