JPG to PDF under 100 KB, 200 KB or 500 KB
Photograph both sides of a certificate, or four pages of a rent agreement, and a portal wants them as one PDF under 200 KB. Ordinary JPG-to-PDF tools embed the 4 MB camera files untouched, so the PDF is 16 MB. KBcut picks the pixel size and JPEG quality for the whole set together so the finished PDF lands just under your cap, with every page as sharp as the budget allows.
Made for
- Front and back of an ID card or certificate as a two-page PDF
- All pages of a rent agreement or sale deed photographed on a table
- Fee receipts and bank passbook pages for scholarship forms
- Screenshots that a portal only accepts as a PDF
How the options work
- Select the photos in the order the pages should appear.
- A4 fits each photo on an A4 page with a 10 mm margin, turning wide photos landscape; Same as image makes each page the photo's own shape.
- The KB budget is shared across pages — more pages means each page gets fewer bytes, so crop tight before selecting.
- Black & white is the single biggest saving for text pages; Greyscale for pages with a photo on them.
- Photos are rotated using the phone's orientation tag, so sideways shots come out upright.
Why a generic compressor gets this wrong
The byte budget is the whole game here. A 200 KB PDF with four pages leaves about 50 KB per page; at that budget an A4 page reads well at roughly 1000 pixels on the long side. With one page the same cap allows about 2000 pixels. KBcut tries a ladder of pixel sizes and qualities for the whole document at once and keeps the sharpest version that fits, instead of compressing each photo blindly and hoping the total works out. If even the smallest step is over the cap, it tells you the smallest size it reached rather than silently handing you a file the portal will reject.
How to do it
- Select the photos, in page order.
- Choose A4 or Same as image, and Colour, Greyscale or Black & white.
- Type the KB cap and press Cut to size. The badge shows the final size; download.
Questions
Can I reorder pages after selecting?
Not in this tool yet — select them again in the right order. Most phone galleries let you tap photos in sequence.
iPhone HEIC photos?
Safari converts them to JPEG when you pick from Photos in the file dialog. If a HEIC file will not open, share it as JPEG first.
Is the PDF searchable?
No — pages are images. Portals accept that; OCR is a different tool.
How many photos can I add?
There is no limit beyond your phone's memory. Twenty pages under a 500 KB cap will look soft — split the upload if the portal allows several files.
One page looks softer than the others.
Every page gets the same pixel budget, so a soft page usually means that photo was taken from further away or out of focus. Retake it close, flat and in daylight.
