This is the place where I push the bot's updates.

[New features] Added /scaleby and /scaleto commands to scale a PDF file

An update has been pushed for fixing forwarded files not being handled.

Restructured the bot's usage. You can now perform most of the tasks simply by sending the bot a PDF file. Make sure you checkout the new usage from /help.

Fixed the bot for sending incorrect scaling info.

[New Feature] Added to compare between two PDF files. Type /compare in the bot to perform this task.

This is an example of the comparison output.

[New Features]
- Added to convert doc, docx, ppt, pptx and odt files into PDF format. Simply send the bot a file that is supported and the bot will convert it for you
- Added a 'Cover' option for PDF files which will give you the first page of a PDF file as an image
- Added a 'To Images' option for PDF files which will give you a compressed file of images of a PDF file

I noticed the bot is unresponsive for some files.

If you run into this problem, please use the feedback command to send me the filename so that I can look into it myself.

In the meantime, please try to change your filename to contain only English characters if this issue happens.

This issue should be fixed now. Please use the feedback command if you still experience this issue.

Converting a file into PDF has been disabled from the bot to prevent unstable behaviours of the bot. Sorry for any inconvenience.

[New Feature] The bot can now extract images inside a PDF file and sends you a compressed file of images that are extracted successfully.

Please note that telegram bots are limited to download files up to 20 MB in size. If your PDF file size is greater than this limit, the bot will not be able to process your file.

[New Feature]
- You can now beautify handwritten notes into PDF format with the bot (Check out the link at the bottom for examples)
- You can also do simple conversion from photos to a PDF file
- Simply send the bot a photo and choose if you'll like to beautify or convert it
- If you want to beautify or convert multiple photos into a single PDF file, use the /photo command instead

[Bug Fix]
- Fixed bot for being unresponsive after performing some of the tasks
- Improved performance after receiving PDF files
