Frequently Asked Questions
What does target size mean?
Target size is the approximate final file size you want after compression, such as 300 KB.
Can I enter size in KB?
Yes. You can enter values in KB and MB depending on your needs.
Will the size be exact?
Not always. The final size is usually close to the target, but exact matching depends on PDF content.
Can I compress scanned PDFs?
Yes. Scanned PDFs usually compress well because images can be optimized.
Does it support large files?
Yes, but very large PDFs may take longer to process depending on the backend setup.
Can I use it on mobile?
Yes. The layout is responsive and works on mobile screens.
Can I upload one file only?
Yes. The current design is built for one PDF file at a time, but it can be extended for batch processing.
What is the quality hint slider?
It helps control the compression strength. Lower values usually give smaller file size.
Will text remain readable?
Usually yes, but aggressive compression can reduce image clarity in some PDFs.
Can I use this in Blogger?
Yes. This HTML structure can be inserted into a Blogger page or custom template.
Can I change the colors?
Yes. You can easily update gradients, buttons, and card colors in the CSS.
Can this be connected to PHP?
Yes. The front end can send the file to PHP for real compression and then return the output file.
