Input, output, and no-upload processing
JPG and PNG inputs are supported and the output is JPEG. Transparency is replaced during JPEG encoding, and complex photographs can require reduced dimensions to pass.
What Readyvio verifies
A passing result is no larger than 100,000 bytes. That proves the Readyvio byte check only; the receiving portal may still apply format-signature, dimension, visual, or account rules.
Common 100 KB workflows
A 100 KB field often appears in job applications, university registrations, account profiles, exam forms, and general upload portals that want quick, predictable transfers. It may be paired with exact pixels or a minimum dimension, so record every requirement before you change the image.
Readyvio treats 100 KB as 100,000 bytes and reports the measured result. That explicit byte check is more dependable than a quality percentage because image detail, noise, and dimensions all affect the encoded size.
Balance readability and file size
Use the original as your source, crop away irrelevant background, and avoid repeated JPEG saves. The preset lowers quality first and may reduce dimensions only when the byte ceiling requires it. A simple, evenly lit image usually retains more visible detail than a noisy or highly textured one at the same size.
Inspect the actual download, not only the in-page preview. Look for ringing around letters, soft eyes, blocked shadows, color shifts, and clipped borders. If any required detail is lost, check the destination’s minimum dimensions or ask whether a larger limit is available.
Privacy and format checks are separate
Compression is not an exhaustive metadata-removal step. Re-encoding may remove common fields, but GPS, device, author, and editing data deserve their own inspection when privacy matters. Use the metadata viewer or removal workflow and treat its bounded verification honestly.
The output is JPEG. Transparent pixels are flattened, and a portal that accepts only PNG will reject a technically valid JPEG. Confirm format, dimensions, composition, and bytes together before submitting.
Leave room below the ceiling
A result that is a few bytes below 100,000 can still be fragile if the destination rewrites the file, applies a second upload check, or uses a different KB definition. When quality and dimensions allow, aim for a comfortable margin rather than maximising the number. Never sacrifice required detail simply to create a smaller buffer.
If the portal reports a different size after upload, compare the exact downloaded file and its encoded format. Keep the original available, record the portal’s message, and use that evidence to choose the next permitted change.
