If I turn my price list PDF into images, does that stop competitors copying the text?
It only stops the easy copy. An image has no text layer, so nobody can select your prices and paste them into a spreadsheet, or search them. A competitor can still retype them in a few minutes or run the image through optical character recognition. Treat it as a small hurdle, not protection.
What actually changes when the list becomes a picture
- Text cannot be selected with a mouse or a long press on a phone, so there is no direct copy and paste.
- Nobody can search inside the image for a product name or a price.
- Text extraction tools that read the text layer get nothing, because it is gone.
- The figures and names are still perfectly visible, which is the whole point of a price list.
In other words, you raise the cost of copying from two seconds to a few minutes. That may deter a casual browser, but not a competitor who is set on knowing your prices. OCR is built into many phones and apps these days and reads a clear image easily.
The price you pay
Before converting, know what it costs you with genuine customers. A buyer who wants to compare two prices cannot search the list. Someone using a screen reader will not hear the prices. The image is heavier than a text PDF, and small figures blur if you choose a low DPI. For a long list, think twice.
A better approach: watermark, then convert
If what you really want is for the list to be traced back to you, or to know who leaked it, a watermark helps more than hiding the text. Add your store name, or the recipient's name, with PDF watermark, then turn the pages into images. The mark becomes part of the picture itself, it cannot be deleted as a separate layer, and anyone who reposts the image reposts your name with it.
- Watermark the price list file, for example For Al Noor Trading only, at a light opacity.
- Open the resulting file in PDF to images.
- Choose PNG and 150 or 200 DPI so the prices stay sharp.
- Convert, download and send the images to the customer.
When you genuinely need protection
If the prices are a real trade secret, the answer is not the file format but who receives it. Send special pricing only to those who need it, and agree on confidentiality in writing if necessary. Anything that appears on a customer's screen can be photographed, whatever its format.
Common questions
Does an image prevent screenshots?
No. No file format can stop a screenshot or a photo taken with another phone.
Is any hidden text left inside the image?
No. The output is pixels only and carries none of the text layer that was in the PDF.
Which format suits a price list?
PNG keeps figures sharp and is the best fit for a list that is mostly text and tables.
