Photo Resizer KB & Signature

Compress photo and signature to an exact KB size for online forms - offline, on your phone.

Portals reject files that are even 1 KB over the limit. SizeReady is a photo resizer in KB that hits the exact file size you type - no guesswork, no repeated tries, no upload to any server.

COMPRESS PHOTO TO EXACT KB
- Compress image to 20KB, 50KB, 100KB or 200KB - or type any custom target from 10KB to 1MB
- Presets for the sizes forms actually ask for: 10, 15, 20, 50, 100, 200, 500 KB and 1 MB
- Reduce image size in KB while keeping the highest quality that fits
- Convert MB to KB in one step - a 5 MB camera photo becomes a 50KB JPG
- Compress JPEG and JPG, and export exactly the format the form wants

INCREASE IMAGE SIZE IN KB
- File below the minimum? SizeReady can also increase the KB of a photo to meet a lower limit
- Hit a range like "between 20KB and 50KB" - both ends respected

RESIZE IMAGE IN KB, CM, MM, INCH AND PIXELS
- Resize photo in pixels (like 200 x 230) or in cm and mm with correct DPI math
- Set file size and dimensions together - one export meets both rules
- Dimension and DPI tools are free, not paywalled

SIGNATURE RESIZE AND CLEANUP
- Signature resize to 10KB - 20KB or any exact size - no minimum
- Common specs built in, like 140 x 60 pixels or 6 x 2 cm
- Scan your signature with the camera: white or transparent background, darkened ink, then resize to exact KB

PASSPORT AND ID PHOTO MAKER
- Passport size photo maker with standard document sizes
- Get both outputs: a print sheet (4x6 or A4) and an upload-ready JPG at an exact KB size
- No watermark

HEIC TO JPG (IPHONE PHOTOS)
- HEIC to JPG converter - opens iPhone HEIC photos and converts them to JPG, fully offline
- Perfect after switching from iPhone to Android, or when a form refuses HEIC

PDF COMPRESSOR AND PDF TOOLS
- Compress PDF to 200KB, 500KB or any exact target
- JPG to PDF and image to PDF with a KB limit - scan paper documents straight to a small PDF
- Merge PDF, split PDF, reorder pages

FORM WORKSPACE
- Enter your application's rules once: photo size, signature size, formats, dimensions
- SizeReady checks the whole package and shows what passes and what fails - before you upload

MY DOCUMENTS LOCKER
- Keep your photo, signature and certificates ready on your phone
- One tap creates 20KB, 50KB or 100KB variants whenever a form asks

WORKS OFFLINE, PRIVATE BY DESIGN
- 100% on your phone - photos and documents are never uploaded
- No account, no sign-in, no broad storage permission
- No full-screen ad before your first export

HONEST RESULTS
- The exported file really is the size on the label - verify it in any file manager
- If a target is impossible without ruining the image, SizeReady tells you instead of pretending

Made for online form fill up - job, exam, admission, visa and ID applications - and for anyone who needs a smaller image to email or upload. Photo size reducer, image compressor, KB photo converter and image resizer in KB - in one honest tool.
