How to blur, watermark, and censor files in 2026
People look up how to blur, watermark, and censor files when a clean preview is already the product. Spike puts the treatment on the unpaid view. Blur softens a still. A watermark marks it. Censor hides a video or a PDF. The file you stored is what they get when you mean them to have it.
How to blur, watermark, and censor files in 2026 is one decision: what can they see before they should have the file. A sharp JPEG in a link is a download. A full video in the player is a download. A PDF that scrolls to the last page is a download. The preview has to be worse than the product, on purpose.
Spike keeps the original in the folder and treats the view. You can stack the tools. Blur a still. Stamp a name on it. Cut a video to a few seconds. Show part of a PDF. Payment, if you turn selling on, is what lifts the treatment. A free share can stay treated if they should look and not take.
Pick the treatment for the leak
Each control stops a different way of walking off with the work.
Blur the unpaid still
Blur is a pixel amount from 4 to 48. Four is a veil. Forty-eight is a refusal. Set it so they can still judge light, crop, and whether this is the right frame. Spike does not detect a face and blur only that oval. The unpaid image is what softens. Blur images and sell is the sell-shaped version. You can blur without charging.
Watermark what they are allowed to read
A watermark is a label, up to 48 characters. Your name, the studio, the word preview. It claims the file on the page. It does not hide the picture the way blur does. Use a mark when they should see the work clearly and still know it is not the delivery. Use blur when a clear still replaces the sale. Many folders want both. Watermark files and sell.
Censor what a full play would give away
Censor is the wider word. On a still it is the blur or the bars you are willing to show. On a video it is a preview length from 1 to 30 seconds, never longer than the clip itself. On a PDF it is page one, or a percent of the document from 10 to 90. Censor files and sell. The longer note for video and PDF is censor a PDF and a video.
Treat a folder before you send the link
Upload the real files
The masters. Spike does not bake the blur into those bytes.
Turn on the view you mean
Blur from 4 to 48. A watermark label. A short video. A PDF sample. Stack them when one is not enough.
Open the link yourself
If you would deliver what you see, it is too clean. Soften it or shorten it.
Send that URL
Price it if they should pay. Leave it treated if they should only look. Do not also attach the clean ZIP.
Selling lifts the treatment
If the folder is for sale, checkout is what removes the preview rules for that buyer. Stripe, in GBP, minimum £1. Selling fee 5% on Free and 1% on Pro and Business, plus Stripe's card fee. A client who already paid you elsewhere can have a passworded share of the clean files instead. Charge for a download link.
Show the work. Do not ship it in the preview.
How to blur, watermark, and censor files in 2026 is a treated preview and a clean file behind it. Pick blur, a mark, a short clip, or a PDF sample. Send one link. What Spike is is that split.
Questions
Good to know
No. The treatment is the preview. The file in the folder stays the one you uploaded. After they pay, or when you send them the unlocked download, they get that original, not the blurred or marked view.
