Frequently Asked Questions
How many AutoCAD files can I merge?
You can merge between 2 and 20 AutoCAD files into a single PDF. For larger projects, consider merging in batches.
In what order are the files merged?
Files are merged in the order you upload them. Make sure to upload your drawings in the desired sequence.
How much does merging cost?
You are charged 1 credit per file conversion plus 1 credit for the merge operation. For example, merging 3 DWG files costs 4 credits total.
Can I merge different AutoCAD formats?
Yes! You can combine DWF, DWFX, DWG, and DXF files in the same merge operation. All formats are supported.
What does the setting "Page Size" do?
This determines the PDF page dimensions. Available sizes are letter, legal, A0, A1, A2, A3, and A4.
What does the setting "Include All Layers" do?
When enabled, all visible layers from your CAD drawing are included in the PDF output. When disabled, only the currently visible layers are exported. This gives you control over which drawing layers appear in the final PDF.
Why is it handy to convert my document to PDF?
Converting a file to PDF ensures your document stays consistent and accessible. PDFs lock in formatting, design, and structure, preventing layout shifts that can happen with editable file types. They’re compatible with virtually all devices and operating systems, making them ideal for professional documents, forms, reports, and presentations. PDFs are also easy to distribute; whether through email, downloads, cloud platforms, or QR-codes that let users open a file instantly on their phone.
Will documents lose quality when converted?
Our intelligent software minimizes quality loss when converting documents. As such, documents can be converted without having to worry about quality loss for a great number of times.
Will my document lay-out or format be changed if I convert it?
No; our intelligent PDF software recognizes document layouts and transforms them accurately onto a new file format. Was your lay-out or format not transformed accurately? Consider applying OCR, or applying different customization settings to convert it correctly.
Can I convert a document into PDF and convert it back into original format?
Yes! There are no limits to converting documents, and documents can safely and easily be converted back and forth. Conversion can be handy to edit a PDF document in Word, and later convert it back into an organized PDF format.
How can I merge PDF documents?
To merge PDF documents simply go to our converter, choose the file format you’re merging, and drag and drop the files you want to merge. Then you have the opportunity to edit some settings, press merge, and you’re done! You can download your merged file right away.
Can I customize my PDF documents while converting?
Yes, PDFengine offers various means of customizing your (PDF) documents. Consider adding a cover page, applying OCR, or using PDF/A as output.
Why is the text in my PDF not displayed correctly?
If the text is not copyable, clickable, or searchable, that means the text is not recognized within the PDF. Try uploading your document onto PDFen and applying OCR. OCR technology will make your text readable. In case it doesn’t work completely in one go: apply OCR a second time.
