How to Customize PDF Conversion Parameters Using VeryPDF Rasterize API
Meta Description:
Discover how to customise PDF conversion parameters with VeryPDF Rasterize API and take full control over your PDF-to-image automation workflows.
Ever tried emailing a client a fancy PDF and they say it “looks broken”?
Yeah, that used to be me too.
I’d create a clean, vector-rich PDFcharts, text, branding on pointthen open my inbox the next morning to:
“Hi, the file’s not opening properly on our end.”
Even worsesometimes it looked fine but printed like garbage. Fonts went rogue. Layouts broke.
That’s when I realised: not everyone’s device plays nice with vector PDFs.
I needed something bulletproof. Something I could send to anyone and be 100% sure they’d see what I see.
That’s when I found VeryPDF’s Rasterize PDF API.
And let me tell you: total game changer.
So what is the VeryPDF Rasterize PDF API?
Let me break it down in plain English.
VeryPDF Rasterize PDF API lets you convert your PDFs into “image-like” PDFs.
That means every page becomes a single rasterised image, locking in the lookno font issues, no layout shifts.
It’s part of the VeryPDF Cloud API toolkit, which is built for developers like me who want tight, reliable, no-nonsense control over PDF processing without babysitting every file.
If you’re:
-
Building apps that handle sensitive documents
-
Automating PDF workflows for a business
-
Delivering reports, invoices, or forms to users in different environments
then this is something you’ll want in your toolkit.
Where it’s helped me the most (real-world use cases)
1. Secure client-facing PDFs
I work with a financial services platform that sends out weekly investor statements.
Before using the Rasterize API, clients would sometimes edit PDFs or extract sensitive content.
Now? We rasterise every page before sending.
They can view it.
They can print it.
But they can’t tamper with a thing.
Boomread-only protection without even adding password locks.
2. Fixing PDF rendering issues across platforms
A lot of users open PDFs on phones, cheap tablets, outdated browsersyou name it.
When you’re dealing with vector PDFs, you’re at the mercy of whatever PDF reader they’ve got.
By rasterising the PDF, we ensure they get a flat, image-perfect view.
Same look. Same feel. Every time. No surprises.
3. Reducing file size for quicker delivery
Now here’s something I didn’t expect:
With the ImageWidth and ImageQuality parameters, I could shrink large PDFs down by 4060% without crushing visual quality.
That means faster uploads.
Quicker previews.
And less server load.
Let’s say you’ve got a 10-page marketing brochure.
You don’t want your user waiting 15 seconds for it to open on 3G.
By tweaking the quality, resolution, and widthbam, faster delivery without killing the brand aesthetic.
How easy is it to use?
Honestly? Easier than I expected.
Once you’ve got your API key, you just fire off a POST request like this:
You can plug that into your app, script it, or automate the whole thing.
It’s developer-friendlyno bloated SDKs, no clunky GUIs, just pure REST simplicity.
Customisation options that make it powerful
Here’s where the Rasterize PDF API really shines: you can fine-tune how the conversion works.
Some of the key parameters I use:
-
ImageRes: Want sharp images? Crank this up to 300 DPI. Need smaller files? Drop it to 150.
-
ImageWidth: Great for compressing the overall size while preserving layout proportions.
-
ImageQuality: Think of it like JPEG compressionbalance between size and clarity.
-
Open Password: If your PDF is password-protected, just toss the password in hereno hiccups.
-
Outfile / Infile: URLs for input/outputmakes it seamless to work from cloud storage.
These controls gave me exactly what I needed without fiddling around for hours.
It’s not just about converting filesit’s about controlling the output, every pixel of it.
Why not use other tools?
Good question.
I tried a few before landing on VeryPDF’s API:
-
One tool mangled my page layouts during conversion.
-
Another made the PDFs huge after rasterising. Not ideal for mobile.
-
Some didn’t support password-protected PDFs at all.
But VeryPDF ticked every box:
-
Fast
-
Customisable
-
Reliable
-
Secure
And with their global infrastructure, latency was a non-issue, even when clients were halfway across the world.
Who should use this?
Let’s keep it real.
This tool isn’t for everyone.
But if you’re in one of these buckets, it might just save your week:
-
Developers building document workflows
-
Legal teams distributing read-only court PDFs
-
Financial firms sending uneditable statements
-
SaaS platforms that generate downloadable reports
-
Any business with a “convert > send > repeat” PDF flow
The verdict? This API gave me PDF peace of mind.
It solved my three biggest headaches:
-
Preventing content tampering
-
Ensuring universal rendering
-
Controlling output size and resolution
So yeahif you’re dealing with PDF workflows that need consistency, control, and security, I’d 100% recommend giving VeryPDF Rasterize PDF API a go.
