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.
