Some feedback. Website design is poor. You could definitely do with a designer to make it look nicer. $5000ish a year is a weird price point. It's too expensive for a hobbyist or small dev shop, but too cheap for an enterprise to buy (when you consider the time of working on procurement problems you'll experience). You either need to make it cheap, like $200/yr, or much more expensive. Right now you are in no mans la…

> Website design is poor. You could definitely do with a designer to make it look nicer. Really, in what way? In my view it's clean and simple. > You either need to make it cheap, like $200/yr, or much more expensive. Right now you are in no mans land. Another unsubstantiated statement. How much market research have you done on PDF libraries? Pricing is a sensitive topic and many factors play a role in it. Too many t…

1) In a PDF file, the measure units are Inches. The page size is in inches. Any dimension is in Inches. There can be a bitmap having 200x200 pixels placed at 3x3 inches. Next to it can be a bitmap of 5x5 pixels placed at 5x5 inches. That means, that PDF does not contain any DPI information. It is not needed at all. PDF rasterizer (e.g. a raster printer) can render it at any DPI. Photopea decodes and saves back bitmap…

Don't you mean points, not inches? That's why page dimensions are things like "/CropBox [0.0 0.0 595.27576 841.89001]". PDF points are the same as Postscript points, 1/72 of an inch, that is 25.4/72 mm. So those numbers mean a page 210mm wide and 297mm high: A4.

I spent about three years building the support for PDF into my graphics editor https://www.Photopea.com . While other editors "add stuff on top of PDF", Photopea "chews through" each byte of a PDF, and tries to make as much sense of it as possible. You can rewrite the existing text (with the same formatting), edit bézier curves, edit gradient fills. You can edit bitmaps on a pixel level. You can see the parameters as…

Awesome feature! Is there a way to change resolution during editing? When I zoom in in Photopea, I can see individual pixels of text characters. With some PDFs pixels show up sooner, making text barely readable during editing.

I work in an industry that marks up PDFs extensively (construction) and have wanted to build a bespoke PDF markup tool for a long time. In designing concrete floor slabs, we need to transfer information from our FEA software to a dwg. Currently a blank plan is printed, it’s marked up by hand, and then handed to a drafter to put back into the computer. It’s a very inefficient process. But all the SDKs are stupidly exp…

Wow. Sounds like you seriously need a separate landing page marketing Photopea as an advanved pdf editor.

It is written right when you open Photopea.com :D https://i.imgur.com/zgX380J.png
