Any thoughts why Adobe Acrobat's Action Wizard makes file-sizes larger?

[Todd's keyboard]

Am preparing some pdf's to put on web pages. Using Acrobat X Version 10.1.16 "Action Wizard" to "Prepare for Web Publishing."

The original document is 7.4 MB. The "Prepared" document is 10.1 MB. This is using the default options that Acrobat presents.

Any thoughts as to why? Strategies to lower the file size?

thanks, Todd's bloated keyboard

It's been quite a while since I've done this, but these links should give you the general idea. May take some trial and error.

If I remember right, it's adding a lot of "just in case" stuff so whoever opens the file (regardless of computer, OS, Adobe version) will not encounter any troubles with the file re/fonts & etc.

It usually depends on what is in the PDF and how it was created. I saw the worst performance/bloat when images were not all the same format and/or orientation, and DOCX/PPT/PDF. If you have time, pick it apart. Make all the images the same type/DPI/resolution/orientation/compression. Rebuild and export so you aren't saving a bunch of undo actions and different formatting styles.

Thanks for the advice. Always appreciated.

The batch of pdf's was generated by scanning originals flyers, catalogs, mailings, and reports.

May I assume that Filliam's advice does not apply in this situation. I can see it would be worthwhile if a pdf was generated from different programs from scratch.

Also followed the steps suggested in datbeme's first link. My version of Adobe X seems to go through the steps of reducing the file size with a "Save As" option, but it doesn't actually create the new file. (It's possible I haven't found the file yet. I"m on a different machine now. I could not find the Saved As file I was expecting.

thanks again, T's K

There are some third-party online PDF compressors that work OK. There's a limit to what can be done, particularly if the bloat is due to graphics. I don't have a specific one to recommend, I just google when I need one.

If these are just scans, jpg would be a better option vs PDF.

Scans are just pixels -- so if you are looking for maximum compression with smallest file size, jpg.

Assuming you scanned at 300 DPI color -- make sure they are RGB (not CMYK) and try medium compression. Use a file that has small text as your guide for clarity.

If you have a lot of black and white pages, condisder converting them to grayscale vs RGB.

Were they all scanned in using the same hardware at the same resolution using the same version of Acrobat?

Scanned text takes a lot more space than if you have used OCR.

All good tips. Thanks.

I think I may have just realized that Adobe's Action Wizard to "Prepare for Web Publishing" may be more than just reducing file size. Is it also working to optimize readability for various browsers and versions of Acrobat?

I didn't scan the images. Will have to ask the person who did.

I sent a box of photos and flyers to a guy who wanted them for his master's thesis. The materials have some historical value of New Games and the San Francisco bay area in the '70s and '80s.

The photos came back as jpg files; the flyers are pdf's. I'll have to ask if the pdf's were scanned for OCR.

Thanks again.

I have no idea what's going on when members start talking about graphics stuff. It's all Greek to me.

But I click on almost any and every thread that has a contribution from or is authored by Todd's keyboard.

The infinite number of clever sign-offs both amazes and amuses me.

Thank your for that, T-k.
