Below we show how to shrink one or multiple PDF files to reduce their file size.
- However, files uploaded through your web browser to dropbox.com can support a maximum file size of 50 GB. All of your uploaded files must be smaller than your Dropbox storage space. If you're using Dropbox Transfer, you can send files up to 100 GB (or 250 GB with the Creative Tools Add-On) without having to load the files into your Dropbox.
- Compressing a file is only half the battle. Once you've got your ZIP or RAR file, you still have to put it somewhere. Whether it's an email, FTP, or file server, your compressed file needs to live somewhere before you can send it.Dropbox takes care of everything in.
- There are several ways to share the files and folders in your Dropbox account. Before you share, decide if you want people to be able to edit your file, only view it, or if you need to collect files from someone. Then, decide if you'd like to copy a link directly to your file, folder, or request, or send an invitation via email from your Dropbox account.
- Compress PDF files for publishing on web pages, sharing in social networks or sending by email. Unlike other services this tool doesn't change the DPI, thus keeping your documents printable and zoomable. Select PDF files from your computer or drag them to the drop area. You can upload up to 20 files.
Upload your files

Rather not upload your files and work with them offline?
Try Sejda Desktop. Same features as the online service, and the files never leave your computer.Click 'Upload' and select files from your local computer.
Dragging and dropping files to the page also works.
Dropbox or Google Drive files
You can pick PDF files from Dropbox or Google Drive too.
Expand the 'Upload' dropdown and select your files.
Compress PDF
Click the 'Compress' button and then 'Download' your compressed PDF. Or, click on the 'More options' button for advanced settings.
The compression algorithm does the following:
- Optimizes images
- Removes unused fonts and images
Configure image quality
Images are optimized and saved with a JPEG image quality of 65%.
That is perfect for most scenarios. But, if your need it you can configure a better quality for the optimized images (even if the PDF size will be larger).
Under 'image quality' select 'Good' or 'Best'.
Image resolution (PPI)
Using the standard settings images are optimized to a '72 PPI' resolution.
Working in a scenario where higher image resolution is needed? Click 'More options', then select '144 ppi', '288 ppi' or '720 ppi' as the maximum image PPI resolution.
Grayscale images
For lower PDF sizes, when having a lot of images, you can convert images to grayscale.
Here's an example of a grayscale converted image:
To use this option select 'grayscale' as 'image conversion'.
Faster PDF compression
Print entire screen. Processing each image takes time. A document with many images will take longer to compress.
Compressing smaller images has little effect over the overall document size. The larger images are what we want to optimize. Choose 'Faster' and we'll skip smaller images and only compress larger ones, saving time.
All you need to do to compress PDF document is to drag and drop the original file into the opened tab of your browser, set the PDF compression level and click 'Compress'. PDF Candy will start processing your file right away. Click the 'Download file' button to get the compressed file.
How do I invite people to edit my files?
If you want the people you share with to be able to edit your files, you can share a folder with them. Changes to the contents inside a shared folder are synced with members of that folder almost instantly. It's a great solution to working together on large projects, sharing important family photos or documents, and any other collaborative effort.
How do I invite people to view my files?
If you need someone to be able to see your files, but not edit them, you can send them a link to that file, or you can give them view-only permissions.

How do I collect files from people?

You can collect files from people by creating a file request. Give the request a name and send the link to anyone you want to collect files from. People submitting files don't need a Dropbox account.
