I'm sorry my optimism was in vain.
I'll uninstall the program and wait for a new version that meets my requirements.
Save | Cancel
I forgot to mention that I couldn't enter the license key. I tried, but to no avail. Please address and resolve this issue. I tried converting the files on the program's website, where there is a free conversion page. However, its languages are limited, and the language I want, which is Arabic, is not available.
Save | Cancel
I downloaded and installed the program, and later found out that it supports a limited number of languages, none of which I wanted. The languages supported by the program should have been displayed in the description field. Five hours wasted for nothing.

I am unable to locate to enter the code to activate the program. I have hit on the “Activate VIP” button and I a page with pricing opens. How am I to " Activate " ?

Thanks for GOTD and LightPDF. LightPDF is free, it can help me to convert PNG images to PDF file and then print.
Save | Cancel
Joan, open the PNG image in any viewer including windows built in and choose print and use the printer Save as PDF and there you have a PDF or if you just want to print the PNG then just choose your preffered printer instead of the save as PDF virtual printer... you don't need any 3rd party licensed programs to do what you claim you want to do.

I've referred to the attachment with the Activation Code, but still cannnot find where the Registration Button is. Please Help..... Wombat
Save | Cancel
Activation was not straightforward, but I got through it. Just read and follow each step carefully, don't sign up for the free trial thing, you activate through the program menu after you download and open it.
Thanks for this! I look forward to trying it and appreciate the 1 year license. I don't tend to respond to 6 months licenses.

I am trying to find the ACTIVATE VIP button but I cannot find it. Please help me
Save | Cancel
Activation is somewhat convoluted - read the "ReadMe" file that comes with the install file, and have ready access to the email you provide. App installed and registered fine in the end.
As to "100 granules" question: this app can use AI (think ChatGPT), and that usage imposes some sort of "payment."
Have installed LightPDF, but have NOT used it yet: Question will be whether you CAN use the app WITHOUT AI. If NOT, it is likely not a keeper...

Can somebody from the developer's team help with how to activate the program? Where es the "Activate VIP" bottom that mentions the txt file? Thank you.

Would anyone tell me what "100 computing granules per month" means regarding PDF pages, quantity, or other criteria?
Save | Cancel
No, it's not. The 100 credits work as the currency in processing your tasks within LightPDF — think of them as tokens you spend when using different features. Each task consumes a different amount of credits depending on its complexity. For example, converting a simple PDF might use fewer credits than AI features.

Hey there,
What makes LightPDF v2.15 (\$49.99) different from PDFGear?
Does it offer more features or make things easier to use?
Save | Cancel
quotation from wikipedia:
"Portable Document Format (PDF), standardized as ISO 32000, is a file format developed by Adobe in 1992 to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems.[2][3] Based on the PostScript language, each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images and other information needed to display it. PDF has its roots in "The Camelot Project" initiated by Adobe co-founder John Warnock in 1991.[4] PDF was standardized as ISO 32000 in 2008.[5] It is maintained by ISO TC 171 SC 2 WG8, of which the PDF Association is the committee manager.[6] The last edition as ISO 32000-2:2020 was published in December 2020.[7]
PDF files may contain a variety of content besides flat text and graphics including logical structuring elements, interactive elements such as annotations and form-fields, layers, rich media (including video content), three-dimensional objects using U3D or PRC, and various other data formats. The PDF specification also provides for encryption and digital signatures, file attachments, and metadata to enable workflows requiring these features."
PDF is one thing above all: cumbersome and unwieldy, and extremely difficult to edit later—it was never really intended for that. It's a final format. It's all the more astonishing how many different attempts there are to edit PDF documents retrospectively, something that only rarely makes sense. Perhaps it's so interesting because it's very difficult.

Lichtes Licht,
Indeed - it was a replacement for printing, not editing documents.
Save | Cancel
Lichtes Licht, often official forms are made downloadable in PDF format, without an editor one has to print the document and fill it in manually. Not everyone has a functioning printer, not everyone has good handwriting to legibly and reliably fill in forms manually they may have dysgraphia or some physical disability that prevents that. With a competent PDF editor one can edit the PDF form and fill it in with formal fonts and save it, import an image of your own signature... and upload the completed edited PDF file or take to a friends and print and post it back if the organisation is still in the stone age.

I’ve been using LightPDF for my daily work, and it’s honestly a lifesaver! The tools are super easy to use, whether I need to convert files, remove watermarks, or summarize documents with AI. What I love most is that everything is fast, accurate, and doesn’t require any complicated steps. LightPDF saves me so much time and helps me stay productive every day. Highly recommend it to anyone who works with PDFs regularly!

bobby,
I use PDF 24, the version you run on your own computer, but it lacks the AI slop.
PDFs were meant to be read, not chatted with.
