DocuPub Alternative: Compress and Merge PDFs Without Uploading
DocuPub has been a quick, free way to shrink or merge a PDF for years: pick a preset, upload, download. It sends your file to its server to do that, caps uploads at 50 MB, and its tool pages say nothing about what happens to the file afterwards. TryDocsy does the common jobs inside your browser and can aim for an exact size in KB, but DocuPub still does a few things we don’t, and this page says which.

What DocuPub offers
On October 28, 2026 docupub.com listed four tools: a Document Converter (Word, Excel, PowerPoint and other files to PDF, PDF/A or images), Compress PDF, Merge PDF and Resize/Scale PDF. Every tool page we opened stated “Upload limit: 50MB per file”. The site carries a “© Copyright 1999-2025 Neevia Tech” line and links to Neevia’s commercial PDF software.
The compressor is more configurable than most free tools. Besides four presets from “Low compression, high image quality” to “Maximum compression, very low image quality”, it lets you choose Acrobat 4, 5 or 6 compatibility, set JPEG or Zip compression and a 0 to 100 quality for colour and grey images, and discard bookmarks, annotations, form fields, attachments, hidden layers and more. It can also preserve PDF/A and subset embedded fonts. Resize/Scale PDF changes every page to a preset paper size or a custom size in points, inches, centimetres or millimetres, with a scale setting and a choice of where the content sits on the new page.
Where your file goes
DocuPub is a server tool. You upload the PDF, Neevia’s software processes it, and you download the result (the converter can also email you a link). None of the Compress, Merge or Resize/Scale pages we read state how long uploads are kept or when they are deleted, and we found no privacy notice linked from them. That doesn’t mean files are kept; it means the pages don’t say.
TryDocsy’s Compress PDF and Merge PDF read the file inside your browser tab and write the result there. The PDF isn’t sent to us, so there is no server copy to delete. For an admit card, a bank statement or an ID scan, the retention question never comes up.
TryDocsy vs DocuPub: side-by-side comparison
| Feature | TryDocsy | DocuPub |
|---|---|---|
| Where processing happens | In your browser tab; the file isn’t uploaded | On DocuPub’s server after upload |
| File size limit | 100 MB per PDF for Compress and Merge | 50 MB per file |
| Compress to an exact size (100 KB, 200 KB, 1 MB) | Yes, type a target in KB or MB | No; presets and manual quality settings |
| Text stays selectable after compressing | No; pages are re-rendered as images | Settings act on images and objects, so text should remain text |
| Fine control (compatibility, discard objects, PDF/A) | No | Yes, many options |
| Merge PDFs | Yes, drag to reorder | Yes, add files with Browse |
| Rescale pages to A4, Letter or a custom size | No equivalent tool | Yes, Resize/Scale PDF |
| Convert to grayscale | Yes, separate Grayscale PDF tool | No grayscale option on the compressor |
| Retention statement on the tool page | Not applicable; nothing is uploaded | None found |

DocuPub details are from docupub.com, /pdfcompress/, /pdfmerge/ and /pdfresize/, read on October 28, 2026. We didn’t upload test files to DocuPub, so this page makes no claims about the output sizes it produces.
When DocuPub is the better choice
Use DocuPub when you need its Resize/Scale tool (we have nothing like it), when you want to tune compression by hand, or when the PDF must keep selectable text and only needs to shrink a little. Its settings work on the images and objects in the file, which suits a typed report full of text and a few photos better than our re-render approach.
Use TryDocsy when a form gives you a hard limit, such as 200 KB on an application portal, because you can ask for that size directly with Compress PDF to 200 KB or any other target. It also fits when the file is a scan or photo, where re-rendering costs nothing you’d miss, and when you would rather not upload the document at all. Pick one tool rather than chaining them: Grayscale PDF also redraws pages as images, so running it and then Compress PDF stacks two rounds of JPEG loss. Use grayscale only when the portal asks for a black-and-white scan.
If a portal still rejects the file, our step-by-step guide to PDFs that are too large to upload covers removing pages, splitting and rescanning, with measured results for each.
Frequently Asked Questions
What is DocuPub?
DocuPub (docupub.com) is a free website with four online tools: Document Converter, Compress PDF, Merge PDF and Resize/Scale PDF. Its pages carry a Neevia Tech copyright and link to Neevia’s PDF products, and the compressor and resizer pages offer Neevia’s desktop programs for working locally.
What is the DocuPub upload limit?
Each DocuPub tool page we checked on October 28, 2026 says “Upload limit: 50MB per file”. TryDocsy’s Compress PDF and Merge PDF accept files up to 100 MB each, read in your browser rather than uploaded.
Does DocuPub delete my files after compressing them?
We couldn’t find out. The Compress, Merge and Resize/Scale pages we read make no statement about how long uploaded files are kept or when they are deleted. If that matters for your document, ask Neevia Tech or use a tool that never receives the file.
Can TryDocsy compress a PDF to 100 KB or 200 KB like an exam portal asks?
Yes. You type the target size and Compress PDF returns the largest version it can find at or under it, or tells you when it can’t get there. DocuPub uses quality presets and manual settings instead, so hitting a set size means trying settings until the output fits.
Is there a TryDocsy equivalent of DocuPub’s Resize/Scale PDF?
No. TryDocsy can crop pages and print several pages per sheet (n-up), but it has no tool that rescales every page to A4, Letter or a custom size. For that job, DocuPub’s Resize/Scale PDF is the better choice.
Will my text still be selectable after compressing?
On TryDocsy, no: Compress PDF re-renders each page as an image to reach the target, so the text is no longer selectable or searchable. DocuPub’s settings work on the images and objects inside the PDF, so text should stay text there. If you need selectable text and the file only has to shrink a little, DocuPub or a desktop optimizer is the better fit.
