Many people are worried about security when using online PDF tools. Even if the files to be processed are not very important, they are still worried. AvePDF to be introduced in this article is a good new choice. It boasts high security. All transferred files will be encrypted and automatically deleted within 30 minutes. You can even delete them manually. More importantly, it provides more than 50 free PDF tools, and the size of a single file supported is larger than other PDF websites.

The AvePDF website provides dark mode, which I quite like, and it also supports Chinese, so friends who are not good at English don’t have to worry about not being able to understand. There are seven categories in total, namely Most Popular, Exchange, Organization, Editing, Protection, Optimization and Others. The translation part seems to be translated by machine, so some of them may be translated a little strangely.
After entering the homepage, the most popular tools currently are compressed PDF, eSign PDF (electronic signature), convert PDF (supports more than 100 file formats), merge PDF, organize PDF, edit PDF, etc. In particular, these two tools include PDF/A verification and PDF/A conversion:
Conversion means conversion. Here are tools for converting other files to PDF (or vice versa), such as PDF to TIFF / JPG / PNG, or reverse Word / Excel / PowerPoint / TIFF / JPG to PDF. It also supports converting text to PDF, and converting PDF files to grayscale, which is relatively rare. In addition, this website will continue to add new PDF tools, which is quite good:
In the editor, you can find crop PDF, resize PDF, clean PDF size, watermark PDF, mark PDF, extract PDF pages, delete text, and edit PDF metadata:
There are currently only 4 tools for protection, including the eSign PDF mentioned earlier, as well as protecting/unlocking PDF, and editing PDF. The tools in this editing option seem to be different. The description states that they are used to delete sensitive data:
In the optimization section, you can find super-compressed/compressed PDF, repair PDF, OCR PDF, delete PDF content, and optimize for the Internet. It must be said that this website provides many special PDF tools. Even compression is divided into two technologies, one is MRC and the other is linear optimization:
Finally, there are two tools for reading barcodes and document viewers:
Once you find the PDF tool you want to use, you can drag in the file, which supports up to 128MB. You can also import files from Google Cloud, Dropbox and links:
And every tool I tested seems to have some settings that can be adjusted, such as ultra-compressed PDF, where you can choose the compression level:
I tested that this PDF file was reduced by 0.6MB after compression. It was originally about 1.7MB:
After downloading the file, you can directly click the trash can on the right to delete it manually, or you can wait 30 minutes for the server to delete it by itself:
If the deletion is successful, a prompt will pop up:
