Image Crop, Rotate & Watermark

Straighten scanned documents, cut out exactly the section you need, and stamp your own watermark — all in your browser with the Canvas API. Drag on the preview to crop (mouse or touch), use the buttons to rotate or flip, then export as JPG, PNG or WebP. No uploads, files never leave your device.

Quick Answer: How do I crop a document for a portal upload?

Load the image, drag on the preview (or type exact X, Y, width and height), tap a document preset — A4 page, passport/GST photo 35×45, square stamp or signature strip — rotate or flip to straighten, add an optional watermark, then press Apply Edits & Download. This free image editor runs entirely in your browser, so invoices and ID scans stay on your device. Note: e-Sanchit itself accepts PDF only (under 1 MB, about 75 KB per A4 page, max 13 pages) — edit your scan here, then use our OCR PDF Generator to build the portal-ready PDF. For bank, GST and email image uploads, JPEG is the safest output.

1

Crop, Straighten & Watermark

Drag the crop box or tap a preset ratio, rotate/flip to straighten, then stamp a text watermark with your chosen position, size and opacity.

Your edited image and export details appear here.

Privacy first: every edit happens in your browser via the Canvas API. Files never leave your device — safe for confidential scans and internal approvals.
Portal tip: for e-Sanchit, remember ICEGATE accepts supporting documents as PDF only (under 1 MB, ~75 KB per A4 page, max 13 pages) — crop and straighten your scan here, then assemble the PDF with the OCR PDF Generator. For bank, GST and email image uploads, JPEG is the safest output.
Typical uses
  • ● Straighten a crooked scan of a signed document
  • ● Crop a photo of a cheque or invoice to the document area

Next step: need a specific file size or different format? Use the Image Compress & Resize tool for exact KB targets and the Image Format Converter for formats. For e-Sanchit’s PDF-only rule, turn your edited scan into a ≤1 MB PDF with the OCR PDF Generator — and sign the final document free with the PDF Signature Pad.

What is Image Cropping and Watermarking?

Cropping removes the outer areas of an image so only the part you need remains — the document itself, without the table background, fingers or shadow edges that get photos of invoices rejected. Watermarking overlays semi-transparent text (a company name, “CONFIDENTIAL” or “FOR BANK USE”) onto the pixels, so anyone who forwards the file can see its status at a glance. Scans and phone photos are also frequently rotated or mirrored; this editor straightens them with pixel-perfect 90° rotations and flips. Everything runs locally with the HTML5 Canvas API — images are never uploaded, which matters when the file is a signed invoice, a bank statement or an identity document. A typical EXIM workflow: crop and straighten the scan here, compress it to the portal’s KB limit with the Image Compress & Resize tool, and remember that ICEGATE's e-Sanchit module accepts supporting documents as PDFs under 1 MB (about 75 KB per A4 page, maximum 13 pages) — assemble that PDF with the OCR PDF Generator.

  4. Pick the output format and quality, press Apply Edits & Download, and save the portal-ready image.

Frequently Asked Questions

How do I crop precisely?

Drag on the preview canvas to draw the crop box — the darkened area is removed. For pixel-perfect results, type exact X, Y, width and height values in the fields below the canvas, or tap a document preset (A4 page, passport/GST photo 35×45, square stamp, signature strip) to fit that ratio instantly.

Which crop sizes do export documents need?

Common needs are covered by the preset chips: an A4-page ratio for full document scans, 35×45 mm for passport and GST-registration photos, a square ratio for stamps and seals, and a wide strip for signatures. Tap a chip and the crop box snaps to that ratio, centred on the image.

Is the watermark removable later?

No — the watermark is baked into the exported pixels. Export a copy without watermark text if you need a clean version later.

Will rotating reduce quality?

90° rotations and flips are pixel-perfect. The exported image is re-encoded at your chosen quality setting, so use 90–95% for archival copies.

What editing features are included?

Crop by dragging on the preview or typing exact coordinates, document ratio presets, rotate and flip, and text watermarks with position, size, opacity and colour control. Export as JPG, PNG or WebP.

Are my images uploaded?

No. Editing runs 100% in your browser with the Canvas API — your images never leave your device, making this safe for confidential commercial documents.

Which format does e-Sanchit or ICEGATE accept?

Important: ICEGATE’s e-Sanchit module accepts supporting documents in PDF format only — under 1 MB, roughly 75 KB per A4 page, with a maximum of 13 pages per document. Crop and straighten your scan here, then assemble the PDF with the OCR PDF Generator. For bank, GST and email image uploads, JPEG is the safest choice.

Is the Image Crop & Edit free to use?

Yes. The Image Crop & Edit tool is 100% free for personal and commercial use — no registration, login or payment required.
