Why DocBlender?
Private by default
Your files are processed in-memory and discarded immediately. We never log or store them.
Fast & lightweight
No installs, no plugins. Each conversion runs on a focused server route.
Works everywhere
Built with web standards. Use it from Chrome, Safari, Firefox or your phone.
When DocBlender is the right tool
DocBlender is built for the small document chores that show up in everyday work: the kind of one-off task where installing software, signing up for an account or paying a subscription would take longer than the task itself.
Sending a job application
Combine your CV (Word), a scanned reference letter (PDF) and a portfolio image into a single PDF the recruiter can open in one click — no zipping, no folder of attachments.
Submitting an expense claim
Drop in a folder of receipt photos and Combine to PDF stitches them into one file you can attach to the expense report, with each receipt on its own page.
Signing a contract by email
Open the PDF, draw or upload your signature, drag it onto the signature line and download a signed copy — no printer or scanner required.
Sharing a chapter, not the whole book
Split PDF lets you isolate a few pages from a long report so colleagues only see what's relevant to them, instead of a 200-page download.
Shrinking files for an upload form
Government and banking portals often reject anything above a few MB. Compress PDF and Compress Image bring most files under the limit without visible quality loss.
Tidying scans from your phone
Rotate a sideways scan, enhance a washed-out photo, or convert a HEIC straight from your iPhone into a JPG the rest of the world can open.
Which tool should I use?
A few of our tools sound similar. Here's how to pick the right one for the job.
Merge PDF vs. Combine to PDF
Use Merge PDF when every input is already a PDF and you just want them joined in a chosen order — it's the leanest, fastest path. Use Combine to PDF when your inputs are a mix of PDFs, images and Word documents that all need to end up in one file.
Images to PDF vs. Combine to PDF
Images to PDF is purpose-built for image inputs and gives you one image per page with size auto-fitted. Combine to PDF handles images too, but is the right pick when you also need to throw a PDF or Word file into the same output.
Compress PDF vs. Compress Image
Compress PDF re-packs the whole document losslessly. Compress Image works on individual JPG, PNG or WebP files. If your large PDF is mostly photos, compressing the photos before turning them into a PDF often beats compressing the PDF afterwards.
Sign PDF vs. Watermark PDF
Sign PDF places a signature image on a specific page at a specific position. Watermark PDF stamps text diagonally on every page. They look similar at a glance but solve different problems.
Split PDF vs. Reorder PDF
Split keeps a subset of pages and drops the rest. Reorder keeps every page but rearranges them. Use Split when you want a shorter document; use Reorder when you want the same pages in a different order.
Privacy, in plain English
Every conversion runs as a single stateless request. Your file arrives over HTTPS, is held in memory for the few hundred milliseconds it takes to convert, then the memory buffer is released. We don't write uploads to disk, don't mirror them to a queue, don't log their contents, and don't retain any copy after the response is sent.
We use Google AdSense to fund the site. Ads load lazily next to the tool you came for, never on top of it, and the conversion button is always reachable without dismissing anything. Visitors in the EEA, the UK and Switzerland see a consent banner where you can choose between personalised and non-personalised ads; everywhere else, non-personalised ads load by default until you opt into more.
We don't require a sign-up, don't store accounts, and don't profile users across visits. The full detail of what cookies are used and how to change your choice lives in our privacy policy.
Common questions
Is DocBlender really free?
Yes. Every tool is free to use without a signup, without a watermark on the output and without a cap on conversions. The site is supported by unobtrusive Google AdSense placements.
Do I need to create an account?
No. There is no signup, no email verification and no profile to manage. You land on a tool, drop a file, get a result and leave.
Are my files safe?
Files are uploaded over HTTPS, processed in memory and discarded immediately. We do not store, log or share your documents. The tool runs the same way for everyone — there's no premium tier that gets different handling.
What's the maximum file size?
Each tool's workspace shows its current per-file and total-batch upload limits. We sized them to cover the overwhelming majority of everyday documents while keeping conversions fast.
Why is conversion sometimes a server call instead of in the browser?
Some operations — like PDF to Word text extraction or Excel rendering — depend on libraries that are too large or too slow to run client-side in every browser. Where that's the case, the file is sent to a stateless endpoint that processes and immediately discards it.
Can I use DocBlender on my phone?
Yes. The whole site is responsive and the file picker hooks into your phone's camera and gallery, so you can scan a receipt, drop it in, and download the result without leaving the browser.
What languages do you support?
The interface is translated into English, German, French, Italian and Portuguese. You can switch language from the menu at the top of any page.
