This guide is aimed at explaining how PDF compression works and what to pay attention to in case you want to try PdfEditly's service.
What Does It Mean to Compress a PDF?
PDF compression refers to the reduction of data contained in a PDF file. This helps in ensuring that the file is smaller in size and not hard to read or work with. A PDF file contains different things like text, images, diagrams, scans, and other items. The presence of large images and scans makes the file larger in size. When PDF compressor, the software reduces the data in the file.
For instance, suppose your report has 30 pages and many pictures. The size of the report could be too large to be uploaded using an online form. In such a case, the compression process might make the size of your report smaller such that you can upload it easily. It is important to realize that when you compress a file, you do not delete any pages.
This depends on the original PDF file as well as on the process used. A PDF containing many images will be reduced more than a text file. A compressed PDF will not change very much at all. In case your intention is to reduce PDF file size, it is advisable to look at the size of the file as well as its quality.
How to Compress a PDF Online for Free
One can use the PdfEditly Compress PDF tool to compress the size of a PDF file within the web browser. The following are the necessary preparations needed before using this tool.
Step 1: Open the Compress PDF Tool
Visit the PdfEditly website and use the Compress PDF tool. Ensure that you have the document that you intend to compress prepared on your computer/device. It is important to ensure that you have opened the right document, especially if you have many documents with similar titles.
Step 2: Select Your PDF File
Select your desired PDF file from your computer or phone. You can take help from the file selection feature displayed on the tool page. Verify the name of the file before proceeding further. In case the selected file consists of many pages, it should be the complete file instead of an old or incomplete one.
Step 3: Choose a Compression Level
PdfEditly offers Low, Medium, and High compression settings. You should select the suitable one available. If preserving the image quality is important, you should go for a milder setting if the tool provides one. If the purpose is to reduce the size of a bulky file, then you should opt for a tougher setting. The outcome may vary from file to file. You should not have the same expectations from each file.
Step 4: Compress and Download the PDF
Begin the compression procedure and let it complete. Once the compressed file is generated, then download the same on your device. Give it a unique name to differentiate it from the old file. For instance, you may give it a name such as "Report-Compressed.pdf".
Which PDF Compression Level Should You Choose?
This depends entirely on the intended use of the document. If the file is meant for one’s personal notes, then the level of compression may be different from what you would use in making a report that is going to be shown to a customer. The low level of compression could work well for those documents whose original look is to be preserved.
Moderate compression can serve as an excellent starting point while working with documents on a daily basis. However, prior to setting the desired compression level, consider your priorities. Should the document include small print, graphs, and complex images, verify them after compression. Should the document be sent solely for the purpose of reading, a
smaller size will matter more than high-quality images. It should also be noted that one needs to verify the initial file size. In case the document is suitable for uploading due to its adequate size and clarity, there is no need to compress it further. The key to make PDF smaller is to set a compression level appropriate for file size and readability.
How to Make a PDF Smaller Without Losing Important Details
You may use a number of techniques to get good results from your compressed PDF. First of all, you should keep the initial version of the document as an alternative source. Then, analyze the content of the document. It may be necessary for you to know whether the document has big photographs or it consists mostly of text.
In addition, scanned pages may influence the process, since each page has its own picture. Lastly, pay special attention to the most important part of the document. Carefully read small text, check figures in tables, and examine pictures and diagrams. If you want to print your document, then check whether it is appropriate for printing.
Here are some useful verifications you can do after compression:
- Text: Ensure that letters and small words are legible.
- Images: Ensure that images and graphs are still easily comprehensible.
- File size: Ensure that the newly generated PDF meets the file size requirement.
PDF size reducer cannot guarantee consistent results on all files. If the document becomes too blurry, then you have to use a lower compression rate if it is an option. Sometimes, you will have to settle for a bigger file just to ensure that critical information remains legible.
Why Is Your PDF Still Too Large?
At times, after compressing a PDF file, there may be no visible difference. However, this does not necessarily mean that anything wrong has occurred. The extent to which a file will be compressed is largely influenced by how the initial file was created. A PDF file containing numerous images will likely remain relatively big even after the compression.
Scanned files tend to take up relatively larger sizes compared to text files. If the initial file has been compressed before, the extent to which one will be able to compress the file will be relatively small. The compression ratio will also determine the results. If the compression selected is mild, then the file will not be reduced much in size.
If you have to reduce PDF file size even more, look at the size of the file and assess the quality of the document after each step. If the initial outcome does not satisfy you, try using one of the other compression levels available. Do not compress the file repeatedly without assessing it. The usefulness of a small PDF file becomes questionable when the information within the document becomes difficult to see.
How to Compress a PDF for Email and Uploads
Email providers, job sites, educational portals, and online form fillers might have restrictions on the size of the files that they accept. If your PDF exceeds this restriction, you will be required to compress PDF for email to make it smaller. The first step would be to identify what this limit is for the provider or the website. Compress the PDF and find out its new size. If it is less than the specified restriction, view the PDF to ensure its content is legible.
For instance, a student might need to submit the assignment to the school's portal. A freelancer might have to submit a report on the project to a customer. In both situations, a compact PDF will help. You can also try using a higher level of compression if the file is still larger. Recheck the result after you compress it.
Avoid deleting pages unless you are sure that they are not necessary at all. There are many free online PDF compressor that will help you if you are in a hurry to prepare a PDF for submission. However, remember that the size of the file and other restrictions of the file format should not be ignored.
