Choosing a file tool
This directory groups file tasks by what you need to change: image format or size, PDF pages, or groups of files and structured data. You do not need to know the exact tool name before choosing a category.
Choose by task
Convert or optimise an image before uploading or sharing it.
Start with the exact task and the output required by the destination. A clear goal helps you choose only the settings that matter.
Combine, split, rotate, or reorder PDF pages.
Use the same inputs and definitions when comparing alternatives. Otherwise, the difference may come from inconsistent assumptions rather than the option itself.
Package files or prepare data in a supported text format.
Keep a short record of important conditions if you may need to repeat the task or explain the result to someone else.
How to choose the right tool
- Define the question you need to answer or the task you need to complete.
- Read the relevant definitions and identify which details apply to your situation.
- Use the checklist or links on the page to confirm the information you need.
- For formal, legal, financial, or sensitive matters, verify current requirements with the appropriate source.
Differences that matter
Convert
A real format conversion changes the file data, not just the filename extension.
When you see this item in the interface or source material, confirm its definition instead of assuming it means the same thing in every context.
Edit or organise
Cropping, page reordering, and ZIP packaging change how content is framed or arranged.
This matters most when you compare results or prepare an output for another person. Keep the same definition throughout the task.
Destination requirements
Check file type, dimensions, page count, and size limits before processing.
If the source uses a different unit, naming convention, or rule, convert or clarify it before continuing.
Examples and review points
Convert or optimise an image before uploading or sharing it.
Check the source and scope of the information before applying it. A page can explain a general process without covering every exception.
Combine, split, rotate, or reorder PDF pages.
If two instructions appear to differ, compare their dates, scope, and the situation they address before deciding which one applies.
Package files or prepare data in a supported text format.
When sharing information, include the relevant page or section so the reader can check the context themselves.
Common mistakes and how to avoid them
Identify whether you are working with an image, PDF, group of files, or text data. Do not assume a general page covers every case. Check the scope and the original source for exceptions.
Select the task that matches the required change. Avoid relying on a single sentence without reading the conditions around it; definitions and exceptions can change the meaning.
Open the output and check its appearance, order, and data integrity before submitting. Do not treat old information as current by default. Check update dates and whether a referenced service or rule has changed.
Frequently asked questions
Which tool should I choose?
Start with the goal: image format, image size, image crop, PDF page order, file packaging, or data format.
What is the difference between compression and resizing?
Compression targets file size, while resizing changes pixel width and height. A destination may set limits for both.
When should I merge or split a PDF?
Merge when documents should become one file; split when a document needs to become separate parts. Extract pages when only selected pages are needed.
What should I verify after processing?
Check image quality and dimensions, PDF page order and orientation, CSV or JSON structure, or ZIP contents as appropriate.
Can I process confidential files?
Check the specific tool’s privacy information and follow your organisation’s rules before using confidential or personal data.
A final checklist
- The page applies to the situation being reviewed.
- Terms, dates, and source information have been checked.
- The next action or responsible contact is clear.
- Personal and confidential information is not shared unnecessarily.
Choose the tool that fits
Keep page-specific instructions and current requirements in view when using this information. Where a task involves personal or confidential data, avoid sharing unnecessary details and follow the rules that apply to your situation.
