Best tool with advanced features - PDF Filler Add, edit, share & highlight option in one application. Easy to use and must have application if you publish documents frequently. If you work on PDF files daily it is a must have application. It handles PDF files and let you edit and add content very easily. - Easy to use tools - Add text, edit text, highlight, notes etc. many features in one application - No watermarks which makes it easy to edit and share. It is working good till now and not found any such cons in the application. Conversion of files do takes times and using advance features needs a pro in that. It gets slower with big files.

Pdffiller review Everything is alright, and serves my needs. Good value-for-money fairly easy to use. Cannot easily find all the forms that I want to use. And some I believe are not available.

Kara, The Support Agent The Support Agent, Kara, that helped me with what I wanted to do was very accommodating and friendly. I had not fully explored the features of this application but I needed to get something rather urgently. Kara was very patient in explaining to me all that I needed to do. I am quite impressed with the Support provided by Kara and by PDFFiller itself.

PdfFiller has been a Lifesaver PdfFiller has been a lifesaver! I have a very important legal matter that has a lot of documents that I either have to fill out or submit. All of which either have to be created, modified, filled out, or signed. Since the matter is being handled across the country, its a lot of pressure off me to be able to edit, create, and save these documents.

So far PDFFiller is meeting my current needs and saving me time and money. I am pretty sure there are other features that I could take advantage of if I actually knew what they were. I welcome a webinar to learn more.

I love PDF Filler I love PDF Filler. It took some getting used to but once I figured it, I cant function without it! No printing, no waiting for mail to show up. Turn any document into a PDF, fill it out, signature and all and go straight to Noterize for a 10 minute video Noterization followed by Fax in PDF Filler and ITS DONE! No printing, no scanning, no fax machine, no trip to the bank. and I can store ALL of my business docs safely to be emailed, noterized, faxed, sent by UPS, send to have someone else complete and return, share with multiple people...Even make make your own forms or turn an existing form into a template. Its future times... ACTUAL PAPERLESS SYSTEM! My only issue was the learning curve, It isn't exactly intuitive at first but it also doesn't take too many sessions to really figure it out.

What do you like best? The ease of deleting, adding and reorganizing worksheets in various units of study. What do you dislike? Sometimes when having to edit the same PDF to set it up to where there is only one student's report in a PDF at a time. It saved over the original document and I would have to reupload it. Recommendations to others considering the product: None, just that it can be a huge time saver for a teacher being able to edit PDFs for the classroom. What problems are you solving with the product? What benefits have you realized? The big one has been being able to send individual progress reports to students. Our gradebook system does not save them in separate PDFs, it saves them all in one so being able to use PDF to separate them and save them individually saves me time.

Document App Optimize: edit PDF documents from anywhere

Using the right PDF editor is important to improve the workflow.

If you hadn't used PDF for your business documents before, you can switch anytime — it's simple to convert any other file format into PDF. This makes creating and sharing most document types easy. You can create a multi-purpose file in PDF to replace many other documents. That’s why the Portable Document Format perfect for basic presentations and easy-to-read reports.

Though many online solutions provide PDF editing features, only a few of them allow adding digital signatures, collaborating with other users etc.

Use pdfFiller to annotate documents, edit and convert them into other formats; fill them out and put an e-signature, or send to other people. All you need is a web browser. You don’t need to install any programs.

Use one of the methods below to upload your document and start editing:

01
Upload a document from your device.
02
Upload a document from a cloud storage (Google Drive, Box, Dropbox, One Drive and others).
03
Browse the Legal library.
04
Open the Enter URL tab and insert the hyperlink to your sample.
05
Search for the form you need from the online library.

Once you uploaded the document, it’s saved in the cloud and can be found in the “My Documents” folder.

Use powerful editing tools to type in text, annotate and highlight. Add fillable fields and send documents for signing. Change a document’s page order. Add and edit visual content. Collaborate with other users to complete the fields. Once a document is completed, download it to your device or save it to the third-party integration cloud.

Answer: To optimize a PDF usually means to reduce the size of the files so that they are more optimal for Internet use. If you work with PDF files, there is a good chance this will be useful to you. By shrinking the size of the file, you can now send the PDFs as email attachments or even a bulk of them.
Most PDF editing/creation software offer an option called Fast Web View or Optimize that allows PDF files to display the first few pages of the PDF file when the document is opened, instead of waiting for the full file to be available. Optimized files are also generally smaller than non-optimized files.
Reduce Size PDF is one particular set of settings of the Optimizer. And it is some average setting, but it may or may not really work for you. Optimized PDF is controlled via the Optimizer, where you have full control over the settings, such as image resolution reduction, font embedding, etc.
Locate the PDF file you want to make smaller. Click on and hold the PDF file. Drag the PDF file to the Drop PDF here icon on the screen. The file will upload and begin compressing. Scroll down and click on Download File Now. Select the location where you'd like to save the file. Click on Save.
