Want to share a taste of a long PDF without handing over the whole thing? A short sample often tells readers enough to decide. The PDF Preview Generator copies the first few pages of your file into a small teaser PDF.
This tool helps authors, sellers, and teams who share reports or ebooks. You upload one PDF, choose how many pages to keep, and download a trimmed sample. The whole process runs in your web browser.

What the PDF Preview Generator Does
The tool builds a new PDF from the opening pages of your file. It copies whole pages, so text and images stay sharp.
- Takes one PDF: you load a single file to sample.
- Sets a page count: the Max Preview Pages box accepts 1 to 10.
- Copies from the front: it always keeps the first pages, in order.
- Caps at the real length: a short file is kept whole, not padded.
- Downloads a sample: the result saves as pdf-preview-sample.pdf.
How to Use It, Step by Step
- Click the upload box to open your file picker, or drag a PDF onto the box.
- Choose the PDF you want to sample.
- Wait for the status PDF loaded. Ready to build teaser preview.
- Set Max Preview Pages to any number from 1 to 10.
- Click Generate Teaser & Download.
- Save the file named pdf-preview-sample.pdf.
How It Works
The tool reads your PDF with pdf-lib, a browser library. It makes a new empty PDF and copies your first pages into it.
Upload PDF→Set page count→Copy first pages→Download sample
No file is sent anywhere. The reading, copying, and saving all happen on your device. The library loads once from a public code network.
Sofia has a 48 page ebook and wants a three page taste for her store. She clicks the box, picks ebook.pdf, and sees PDF loaded. Ready to build teaser preview. She leaves the count at 3 and clicks Generate Teaser & Download.
Her browser saves pdf-preview-sample.pdf with the first three pages. The status then reads Done. Your 3-page sample download has started. The sample opens like any PDF, ready to upload to her shop.
How to Read the Result
The sample PDF holds only the pages you chose. They match the original exactly, with no watermark added.
The page order is unchanged. The tool always starts at page one and counts forward.
The file size drops because most pages are gone. A short sample is quick to email or post.
Good Ways to Use a Sample PDF
A teaser works well for paid ebooks, courses, and reports. Readers see the opening, then decide whether to buy the full file.
Samples also speed up reviews and approvals. A manager can skim the first pages without downloading a large document.
A real PDF sample often beats a screenshot. Readers can scroll, zoom, and select text just like the full file. Keep the count low so the teaser stays small and loads fast.
Pick a page count that shows value without giving the whole file away. For an ebook, the first three pages often cover the cover and opening. For a report, one or two pages may be enough.
Because the sample is a normal PDF, it works on any device or reader. There is no special viewer to install.
If you need a specific middle section, this tool is not the fit. Use the split PDF tool or pull an exact range of pages by number. To keep only chosen pages, try the selected pages merger.
Before you sample, you can count the pages to plan the size. Afterward, compress the sample for faster sharing. See more tools in the PDF Tools hub.
Limitations and Assumptions
- The tool keeps only the first pages, not a chosen middle range.
- It makes a PDF sample, not an image preview or an embed code.
- A password protected or damaged PDF cannot be sampled, and the tool shows a clear message.
- Every run saves the same name pdf-preview-sample.pdf, so rename files you want to keep.
- The tool keeps no copy, so upload again for another sample.
FAQs About the PDF Preview Generator
Does This Tool Upload My PDF?
No. The sample is built in your browser with JavaScript. Your PDF stays on your device.
Does It Create an Embeddable Preview or a Link?
No. It only produces a downloadable sample PDF. There is no embed code or hosted link.
Which Pages Does It Keep?
It keeps the first pages, in order, up to your chosen count. It cannot pick a middle section.
What if I Ask for More Pages Than the File Has?
The tool keeps the whole file. It never pads the sample with blank pages.
What if I Enter a Number Below 1 or Above 10?
The tool keeps your page count within 1 to 10. A blank or invalid entry falls back to 3 pages.
Is a Watermark Added to the Sample?
No. The copied pages match the original with no extra marks.
This tool runs in your web browser and may not handle every PDF file, font, or browser the same way. Keep a backup of your original file. Reviewed for general accuracy by Prof. Dr. Khalil Mudassar, PhD.
