stirling-pdf's Issues

[Bug] Detect/Split Scanned photos needs scripts under root /scripts

"Detect/Split Scanned photos" searches for the script "split_photos.py" under root /scripts/ and not under the Stirling-PDF install folder ./scripts/. This may work in docker installations but needs to copy or symlink the scripts folder to / in standard installations.

Feature Request: pdf to .xls, .doc (Update: Done for .doc, .xls still remaining)

Hey mate, thanks for this project, it is probably the single most useful docker image out there.

Have you considered adding functionality to convert pdfs to word (.doc) and excel (.xls) file types.

Change contrast option on existing PDF

Great project first and foremost!

I had been looking for a replacement for the aging zpex/web-pdf-toolbox (https://hub.docker.com/r/zpex/web-pdf-toolbox) - since it has not been updated since 10/07/2021 - An as of recently I've had to re-pull or restart it to get things working again.

So Stirling-PDF was perfect timing.

One of the options that the Zpex project has is the ability to adjust the contrast on existing PDF. Might this be a feature/function that could be added at some point in the future.

Again great project and thank you for your time and consideration.

Error when filename contains non-English characters

Hi, when I try to merge or rotate pdf files with Chinese name, the site returns error 'contentType is null'
Here is the log:

Put Results in New Browser Window (or some sort of modal) instead of same Window

Would help a lot when you have to do more than one Task.

BTW: Great Tool! Love it!

Struggling with Rest API

Hello there, first of all, congrats for such a nice work.

Since I can do a curl to rest api im testing if I can remove password from there; it works well from web ui but as I have lots of files with password I would like to use the API and make a script to remove passwords from all files.
Im not going deep in the script here, but I post the api call:

curl -X 'POST' \
  'http://192.168.2.43:8087/remove-password?password=actualpdfpassword' \
  -H 'accept: */*' \
  -H 'Content-Type: multipart/form-data' \
  -F 'fileInput=/share/Container/pdf/07.pdf;type=application/pdf' \
  -o '/share/Container/pdf/NO_PASS.pdf'

it creates a 0Kb NO_PASS.pdf file

here the command from my actual instance: http://192.168.2.43:8087/swagger-ui/index.html

curl -X 'POST' \
  'http://192.168.2.43:8087/remove-password?password=actualpdfpassword' \
  -H 'accept: */*' \
  -H 'Content-Type: multipart/form-data' \
  -F '[email protected];type=application/pdf'

what Im doing wrong here? any suggestion?
Running Stirling-PDF from docker BTW

Thanks so much in advance!

Support for Reverse proxies

I would really appreciate if you could add support for reverse proxies like Apache, Caddy, Traefik and others.

To support reverse proxies in spring boot according to the docs what you have to do is simple.
Add this line to the application.properties:
server.forward-headers-strategy=NATIVE

[Feature Request] - Rest API

Hi,

I was just wondering if there were any plans to provide an API interface, where I can e.g. post a pdf and ask it to remove pages 2, 4 and 7 etc.

[Feature Request] - Mapped Volume and Batch processing

Hi

Just wondering if there was anything on the road map to support mapped volumes via docker, so there is always a default source, one that could also be used for batch processing. Do XYZ to all PDFs in /folder/.

[Feature request] Url to pdf

Idea: Removing/deleting pages from PDF

It would be great to have ability to delete pages from multipage PDF document.

Login / Restriction

An option to restrict the access or a login would be great.

OCR Doesn't seem to make the PDF searchable

After using OCR on a PDF with a scanned image, the resulting pdf also has just a image, no searchable or text I can copy.
If I select the option to Produce a text file along with OCR, I can see that the OCR process does run, it just seems the output PDF does not contain this information.

If I use the option to forceOCR on all pages, then even pages that were searchable are now not.

I am running Stirling-PDF on docker, lastest tag as of 27/04/2023.
App Version 0.6.0
Tesseract Model - tessdata eng (the bigger one, not fast)

Is there support for aarch64?

I'm running Ubuntu-20.04-aarch64 on Oracle Free Tier and when trying to start the container I get "exec /bin/sh: exec format error".
Am I doing something wrong or is it just not supported?

Improve Add image (for signatures etc)

Maintain metadata and bookmarks

Remove Password doesn't work

As the title says, Remove Password doesn't work. It just gives me a smaller file, albeit still being password-locked.

Remove Pages - URL incorrect on Home page

Remove Pages on home page redirects to /remove-pages which throws error

It works from top navigation as it redirects to /delete-pages

I believe it should be remove-pages and top nav should match that to be consistent with naming conventions

Cheers!

OCR'ed PDF does not show OCR text when converted to DocX

Copy Stack Trace does not work without Showing Stack Trace first

Copy Stack Trace buton copies nothing if you do not click show stack trace first.
IMO it should still copy even if I dont want to see on screen. especially an issue on mobile browsers.

Application Logo

Hey

I like your project a lot and I want to add it to the service list in Kubero. This will allow users an easy installation on a Kubernetes cluster. But I need a (more or less) square icon/logo .

Fix compression with Locale error

Translations

I would like to translate Stirling to Polish. Earlier in other systems I use Weblate. Maybe You would consider to make Your app multilanguage and set new projest in weblate

Error 400 adding Watermark

Hi,
when adding watermark I am getting following error:

I have standard Docker installation.
I am getting following error in logs:

Seems like PDF file is not linked properly in form?

Compression does not always reduce the size of files??

I think that the pdf compression to reduce the size does not work correctly or not always with all types of pdf, possibly it is not able to reduce the quality of the images to 150dpi or similar. Is this failure possible or is it a limitation? I tried to compress to reduce the size of 3mb using any of the 3 options and all exports left the file size practically the same. But using PDF4me (API mode with app or automation) has been able to reduce it to 800kbs (web mode) and 1.5mbs (print mode). I include the pdf that you can try to try the compression. Thanks anyway, your project is very good, very useful and I love it!

[Feature request] Add page numbers

Idea: PDF document preview

It would be great to have some form of preview for PDF. Now when I want to ie: rearrange PDF i need to check locally what pages I need to rearrange and than provide that in StirlingPDF. It would be great to do this interactively.

[Feature request] repair pdf

Enhancement: with new download features error reporting needs fixing

Feature request: Multitool - Add page numbers for each page

Useful for when the you the page number.

PDF to Image only does 1st page.

expected - It should be converting all pages to separate images as per my understanding.

[Feature request] redact text

[Feature request] bulk rename based on title

add rotate pages feature

There is a typo in the new image to pdf implementation

The field for selecting images has a wrong label/placeholder

Expected behaviour:
The field says "Select Image(s)"

Actual behaviour:
The field says "Select PDF(s)"

How to reproduce:
Visit the page for the image converter, read the label.

Better visual feedback of downloads

Feature request: OCR

Firstly - thanks for this neat project, I was looking for exactly something like this few days ago.

Would it possible to add OCR as one of the tools? There's a good working CLI tool called OCRmyPDF so maybe it wouldn't be too hard to implement.

Feature request: Image extraction from PDFs

First of all, thanks for your work on this excellent project.

For my workflow a feature to extract the pictures embedded in a pdf would be really helpful. Because I need this feature somewhat often I still have to use a desktop pdf editor.

Thanks in advance

Missing Output Types

Missing JPG, GIF formats for PDF To Image. Was in previous version. Running Latest Update.

Metadata remove all issue

Matadata removal all reported to not work

Feature request: Multitool - Bookmark Passthrough

Some PDFs (mostly documents) have embedded bookmarks that let users jump to a specific location. Currently if parsing a document, any existing bookmarks are lost.

I don't think the existing pdf writer (Hopding /pdf-lib supports retaining chapters, as it was in the roadmap SEP-2021 Hopding/pdf-lib#998, but the maintainers last contribution on github was NOV-2021.

I found this, Don't know if it's going to be of any use
https://github.com/xianghuzhao/pdf-bookmark

Better error handling in ui

Show stack trace to user or at least error message

Create custom nicer looking error pages as well

[Feature request] markdown to pdf conversion

It would be nice to be able to convert markdown files to pdf, leveraging the formatting capabilities.
As a example, the node package markdown-pdf [1] first converts markdown to HTML and then render it in a PDF.

[1] : https://github.com/alanshaw/markdown-pdf

Enhancement : Change Contrast like camscanner

Thanks for all! its amazing project!

add the possibility to decide the order in which pdf files are merged

Feature request: Remove watermark
