If the PDF Flattener is not quite right for your workflow, these are the alternatives worth considering - what each one does well, where it falls short, and the situation it suits best.
What to Look for in Any Alternative
- Speed to a usable first result on your real tasks, not demo tasks.
- Control over the output: can you steer structure, length and tone?
- Cost against your actual volume, including the free tier you can live on.
- Privacy: what happens to what you paste, and for how long.
- Fit with the tools you already use every day.
The Alternatives
1. Desktop suites
Flatten options inside print and export dialogs.
Choose it when the task is occasional, the material is sensitive, or you specifically want a human or a different kind of tool in the loop. The trade-off is always the same one: more control or more speed, rarely both at once.
2. Print to PDF
Reprinting effectively flattens interactive content.
Choose it when the task is occasional, the material is sensitive, or you specifically want a human or a different kind of tool in the loop. The trade-off is always the same one: more control or more speed, rarely both at once.
3. Our PDF form filler
Complete the form before the flattening step.
Choose it when the task is occasional, the material is sensitive, or you specifically want a human or a different kind of tool in the loop. The trade-off is always the same one: more control or more speed, rarely both at once.
4. Our PDF annotator
Add the marks that will be frozen in place.
Choose it when the task is occasional, the material is sensitive, or you specifically want a human or a different kind of tool in the loop. The trade-off is always the same one: more control or more speed, rarely both at once.
5. Our PDF compressor
Trim weight after flattening is done.
Choose it when the task is occasional, the material is sensitive, or you specifically want a human or a different kind of tool in the loop. The trade-off is always the same one: more control or more speed, rarely both at once.
How to Decide
- Write down the one task you need this to handle every week.
- Try your real material in the {$n} and in one alternative.
- Compare edit time, not generation time - the shorter total wins.
- Re-check the decision in a month; habits and pricing both change.
The Option Nobody Mentions
Keep the PDF Flattener and add a second step. Most apparent alternatives only do a different part of the same job - one produces, another checks, a third formats. Combining two focused tools with a short review in between often beats hunting for a single tool that does everything.
Frequently Asked Questions
What does flattening do?
It merges interactive layers - fields, annotations, comments - into the page content itself.
Can I unflatten afterwards?
No - flattening is one-way. Keep the interactive original if edits might return.
Should I flatten before signing?
No - complete signatures first; any later change invalidates them.
Is my file uploaded?
No - flattening runs entirely in your browser.
