JPEG, or Joint Photographic Experts Group, is a commonly used method of lossy compression for digital images. It is ideal for photographs and realistic paintings, offering a balance of image quality and file size. JPEG files typically come with extensions like .jpeg or .jpg and can significantly vary in size based on resolution and pixel density.

Why shorten JPEG file size to 400kb?

Batch processing allows users to shorten multiple JPEG files simultaneously, which is particularly beneficial for teams handling large volumes of images. This feature saves considerable time and effort, ensuring that all files meet specified size requirements without repetitive individual processing.

Good but very expensive; if I could open and fill PDFs on my computer, I would do so, but my computer, for whatever reason, will not allow me to. Also, lining up the characters/text could be better?? But thank you - it's still a lifesaver!

The service is great and the price for fax service is much less expensive than other companies. I love the fact I can fill out documents then email, fax, or file them away.

It's MUCH EASIER TO USE THAN WONDERSHARE PDFelement 6! Which costs $$$$ more than PDFfiller. I could not use the Wondershare PDFelement 6 and got a refund. However if PdfFiller increases it's costs I will attempt to buy the Adobe program. It's not that I use pdf that often that I have to pay a monthly cost.

Great tool for conversions Converting PDFs to spread sheets can be time consuming. This software is very functional, and eliminates the hassle. I like being able to convert my PDFs into the proper documents for further use. Most PDFs in their original form are totally unusable. I use this function to convert the document into a spread sheet. Great time saver. Nothing so far. Seems to be easy to use and very convenient.
