HEIC to JPG Under 100 KB
Certificates, ID proofs and marksheets photographed on an iPhone hit the same wall as photos — HEIC format plus a size cap, except here the cap is commonly around 100 KB and the thing that must survive compression is text. This page converts and compresses in one step, tuned to keep documents readable.

Documents are the hard case — and the common one
Photo fields want a face; document fields want legible text, stamps and seals — and JPG compression attacks thin dark strokes first. The 100 KB tier exists on portals precisely because document uploads need more room than portraits, and the exact-size engine here spends that room the right way: it prefers keeping resolution (where legibility lives) and moderates quality, rather than shrinking the page into a sharp-but-unreadable thumbnail. It is the same planner behind the 100 KB preset page, fed by the HEIC decoder.
The iPhone half is handled the same as on every page in this cluster: native server-side HEVC decode, rotation applied to the pixels — crucial for documents, which are photographed at every angle — and JPG output because that is what document fields parse.
Photographing a document so 100 KB is enough
Three habits carry most of the quality: fill the frame with the page (crop away the table), shoot square-on in even light (shadows cost bytes and legibility), and photograph one page per file rather than a spread. A well-framed A4 page lands comfortably readable at 100 KB; a skewed, shadowed photo of the same page may not — no compressor can add back contrast that was never captured.
For multi-page sets, batch up to ten files in one run and grab them individually or as one ZIP. If a portal wants a single file for many pages, that is PDF territory rather than JPG — photograph the pages, convert them here, and assemble downstream.
The honest edges
A target that cannot carry a given image at acceptable quality is flagged before compression and still yields the closest possible file — with documents this usually means the photo needs re-taking, not the tool needs re-running. Files already under 100 KB come back untouched and labelled as such. Metadata (camera, GPS) strips by default with a keep toggle, transfers are encrypted, and everything deletes within 24 hours.
Portrait photos for the same application belong on under 50 KB; bulkier scans with a generous cap fit under 200 KB. No cap? The plain HEIC converter converts at full quality.

Download for the portal
Each page lands at or under 100 KB as a JPG — individually or all together as a ZIP.
Frequently asked questions
How do I convert an iPhone photo of a certificate to JPG under 100 KB?
Upload the HEIC here — decode, orientation fix and exact-size JPG compression to at-or-under 100 KB run as one step, tuned to keep document text readable. Download and upload to the portal’s document field.
Will the text on my document stay readable at 100 KB?
For a well-framed single page, yes — the engine preserves resolution first because that is where legibility lives. Dense small print benefits from cropping to the relevant section before uploading.
Does this handle photos of documents taken at an angle?
Rotation stored by the iPhone is corrected automatically. Perspective skew from shooting at an angle is not — photograph square-on for the best result, since skew costs both legibility and bytes.
Is the conversion free and private for sensitive documents?
Free with no signup or watermark. Files transfer encrypted, are processed by machines only, have identifying EXIF metadata stripped by default, and are deleted within 24 hours.
Can I convert ten document pages in one go?
Yes — up to ten files per batch, each compressed to the 100 KB cap independently, with per-file downloads and a download-all-as-ZIP button.
