Batch watermarking for property workflows
Estate agents watermark preview galleries before a listing goes live on the portals. Property photographers brand proof sets so agents can circulate them without unmarked copies leaking. Stampi handles both with the same batch workflow.
New-home developments circulate preview sets to multiple agents before release day. Watermark every hero shot the same way so leaked previews still point back to your site team.
Letting negotiators photographing vacant rooms on iPhone can watermark, convert HEIC, resize, and compress in one visit to Stampi before the train home from the inspection.
Auction catalogues circulated to multiple bidders need consistent proof marks before the legal pack goes out. Same opacity and position across every lot photo signals professional handling.
Developers marketing off-plan sometimes circulate watermarked CGI alongside photography. Same batch workflow applies even when source files come from a render farm rather than a camera.
Practical, not preachy
Nobody visiting this page wants a lecture on copyright law. They want to know whether watermarking forty files takes minutes or an afternoon. With Stampi, you upload, set your logo or text mark, preview on a before and after slider, and export.
Vendor portals on competitive patches sometimes forward unmarked JPEGs to family WhatsApp groups. A visible proof mark reminds everyone which files are not cleared for public use yet.
Opacity at forty percent across the centre reads as proof on a laptop but can look heavy on a phone. Check one exterior on your mobile before sending forty files to a picky vendor.
Trainee negotiators should learn proof versus final folders on day one. Clear naming conventions prevent Friday evening upload mistakes.
Opacity that works on desktop may vanish on a phone in bright sunlight. Quick mobile check on one proof file before sending the full set.
Combine with portal prep
Watermarking is often one step in a longer chain. Stampi can resize to Rightmove dimensions at 1600px longest edge, compress for faster uploads, and convert HEIC phone photos to JPG in the same batch as your watermark pass.
A sensible chain: download the photographer folder, watermark at proof opacity, send to the vendor for approval, then run finals with the agency logo at brand opacity.
One upload zone and one download ZIP beats bouncing between conversion apps and image editors for a standard fifteen to twenty five photo listing.
Rightmove at 1600px sRGB JPG is the usual final step after proof approval. Run both passes in Stampi rather than exporting unmarked finals by accident.
Letting renewals reusing last year's photos still need fresh watermarks if the branch rebranded. Run the archived folder through Stampi with the new proof PNG.
Agency branding versus proof protection
Some franchises supply separate approved logo files for digital versus print. Use the digital PNG for on-image watermarks; print PDFs are often the wrong resolution for overlay work.
Proof watermarks can be larger and more opaque than final brand marks. Final delivery uses the branch logo at the opacity compliance specifies, often around fifty to seventy percent.
Suffix folders PROOF and FINAL in capitals. Sounds obvious until someone uploads the wrong one at 6pm on a Friday. Your future self will thank you.
Some agents use a semi-transparent PROOF text PNG for vendor review and the full colour branch logo for live listings. Keep both files in a shared folder with obvious names.
Honest limits
Screenshots of your Rightmove listing are impossible to watermark after upload. Marks work on files you control before they hit the portal.
Social screenshots of your live listing cannot be watermarked after the fact. Control the files you send, not what buyers screen-grab later.
Video watermarking is not supported in the browser tool. If your branch wants branded walkthrough clips, that needs a different workflow or the Stampi API for automated video processing.
Heavy watermarks on hero shots can deter click-through on the portals. Balance protection on proofs against clean finals for live marketing.
File naming and delivery hygiene
Name batches with the property address and date so recipients know which folder is which. PROOF_12_Oak_Road and FINAL_12_Oak_Road beats IMG_0001 through IMG_0024 in an email attachment.
Photographers who include a one-line note explaining proof versus final files get fewer confused calls from branch admin.
When the vendor approves, run the final batch with the agency logo, resize to 1600px sRGB JPG, and compress sensibly before CRM upload.
Include the property address and date in the ZIP filename so recipients on mobile know what they are opening. Small courtesy that prevents wrong files being forwarded.
CC the branch manager on proof delivery emails so approval is on record before finals go live. Simple paper trail that helps when vendors dispute which version they signed off.
Frequently asked questions
Can I watermark with text instead of a logo?
Stampi overlays your uploaded logo image. Most agencies export their branch name or proof mark as a PNG with transparency. If you need dynamic text per file, that is outside what batch overlay handles. For standard proof marks and agency logos, upload the PNG once and apply across the folder.
Will watermarks show on Rightmove after upload?
Yes, if you export watermarked files and upload those to the portal. The watermark is baked into the JPG, same as any branded export from an image editor. Use proof opacity for vendor review packs and final brand opacity for live listings. Preview before batch processing to confirm the mark reads clearly without dominating the photo.
Can I remove a watermark later?
Not from the exported JPG. Keep unmarked originals in a separate folder or use Stampi's option to export originals alongside watermarked versions. That way you retain clean files for print or re-branding while sending marked proofs to vendors. Plan your folder structure before the first batch so you do not overwrite the only clean copy.
Is Stampi free to use?
Yes. Stampi is free with no subscription, no credit card, and no trial that expires. Open the app, upload your files, and download the results. We built it that way on purpose because photo prep is annoying enough without a paywall in the middle.
Do I need to create an account?
No. Stampi runs in your browser with no sign-up. Images are processed locally on your device. When you close the tab or download your ZIP, the session is gone. We do not store your files on a server.
How do I get started?
Go to stampi.cc, upload your photos (or click Try with samples to load demo files), add your logo, pick your export formats, and hit Prepare Media. A ZIP downloads in seconds. That is the whole workflow.
