Why does the text look soft after conversion?

Because 100KB leaves little room for a camera image. Softness means the search had to go to a low quality or a smaller picture to fit. Re-shoot with better light and a tight crop, or use a greyscale scan from a scanner app; both reach a clearer result at the same size.

Will my PDF ever come out larger than 100KB?

No. The size on the result card is the finished file as measured, and only a version at or under 100KB is offered. If the measured file is 98KB, that is what you download; the converter does not round or estimate.

Can I use a PNG screenshot instead of a photo?

Yes. A screenshot of an e-receipt or an online statement works well here, because flat colours and crisp text compress much further than a photograph. Any transparent area in a PNG is filled with white when the page is built.

JPG to PDF Under 100KB for ID Proofs and Short Forms

A 100KB ceiling usually sits on a single-document field: a photographed PAN card, a signed declaration, the first page of a passbook. It is a tight budget for a camera image, since a phone saves even a plain sheet of paper at 3MB or more, and that gap is the reason this page exists. Drop the picture and the PDF comes back already under the mark, with nothing to type.

Two pages fit, but they have to share the 100KB between them, so a two-page result is softer than a one-page one. For anything longer, or for a document with fine print that must stay legible, use the 200KB or 300KB version of this converter and check whether the portal really insists on 100KB for that field.

Before and after

A smartphone and a ballpoint pen beside a tax certificate on a white folder — One 2400 × 1687 photo of 456 KB became a one-page PDF of 99.2 KB.
Each photo sits on its own A4 page, turned landscape when the photo is wider than it is tall.
The JPEG quality inside the PDF was searched so the whole file stays under the 100KB limit; the photos were scaled down only as far as that needed.
The numbers are from a real run of the tool above. The pictures are previews of the first pages of the actual files.

How to use it

Photograph the document straight on, or pick an existing picture from your gallery. HEIC, JPG and PNG are all accepted.
Add a second page if the form has one, and use the arrows if the pages came in the wrong order.
The conversion starts as soon as the files are in; the result card shows the finished size next to the limit.
Download the PDF, open it once and read the smallest text before you attach it.

How the quality is found

The limit is a hard ceiling. The tool encodes the page at a high JPEG quality, measures the whole PDF, and if it is over 100KB tries a lower quality, narrowing the search until it finds the highest setting that fits. Only when even a low quality is still too large does it reduce the pixel dimensions of the picture and search again. Every candidate is measured as a complete file, so the size on the result card is the size the portal will see.

Why a phone photo is scaled down

A 12-megapixel photo has far more pixels than 100KB can carry at any acceptable quality: around 4,000 by 3,000 of them, when an A4 page at 100 pixels per inch needs only about 830 by 1,170. Keeping every pixel would force the quality so low that letters break into blocks, so the picture is shrunk until a readable quality fits. For an ordinary printed form the words stay clear at the reduced size; handwriting in light pencil is the first thing to suffer.

Taking a picture that compresses well

Bytes go to detail, and a photo of a document contains more detail than the document itself: the table under it, the shadow of your hand, the grain of poor light. Lay the sheet flat, shoot in daylight or under an even ceiling light, and crop the picture to the edge of the paper before adding it. A clean white page with black text compresses to a fraction of the size of the same page photographed on a patterned bedsheet, and that saving goes straight into legibility.
