Choose by outcome, not by file extension
Start with the result you need: a smaller upload, exact pixel dimensions, a compatible JPG, reordered PDF pages, or a visible watermark. Conversion is only useful when the destination actually accepts the output and its trade-offs.
Image workflows
Compression, resizing, cropping, metadata removal, watermarking, and format conversion operate on decoded pixels. Keep the source because a new export may flatten transparency, discard metadata, or introduce lossy compression.
PDF workflows
Page operations copy or render PDF content locally depending on the task. Merging and organizing usually preserve page objects; PDF-to-image deliberately rasterizes each selected page.
Frequently asked questions
Which tool should I use for a strict upload limit?
Use the matching 20KB, 50KB, 100KB, or 200KB image compressor. Leave a small margin because forms may calculate KB differently.
Can I combine several operations in one pass?
Some image workbenches combine resize, format, and quality settings. PDF page operations remain separate so the result and limitations stay explicit.
Do the tools upload files?
Supported operations run in the current browser session. Files and generated results are not sent to the Image PDF Tools application server.
