Increase image
to 1 MB.
Some forms want a photo of at least 1 MB. Drop your image in and the tool adds exactly enough weight to land on 1 MB — the pixel grid stays untouched, and the file never leaves your browser.

01 · The floor
Why a form asks for exactly 1 MB
A 1 MB floor shows up wherever someone downstream plans to print or enlarge: university application portals, stock-photo desks, scholarship forms. They assume a photo that light cannot hold an A4 print — and they are usually right.
Resaving the photo larger is the wrong lever — the form then rejects the new width and height. This tool keeps the pixel grid exactly as it is and only moves the file weight, landing precisely on 1 MB.
02 · The mechanism
How the size is reached
Re-encode at the highest quality those dimensions can hold
The encoder is pushed until the file is as large as your existing pixels allow. These are real image bytes, and they survive a portal that re-encodes whatever it receives.
Top up the remainder with declared metadata
If maximum quality still lands under the target, the gap is filled with a standards-compliant segment — a JPEG comment, a PNG tEXt chunk, a WebP JUNK chunk. Every viewer ignores it; pixel data, dimensions and DPI stay untouched.
Portals that re-encode every upload will strip metadata, and the file falls back to its real-pixel weight. That is why the quality step runs first — bytes carried by pixels survive re-processing; bytes carried by metadata do not.
What stays the same

Questions people actually ask
How do I increase an image size to 1 MB?
Drop the photo in, keep 1 MB selected, and press the button. The engine re-encodes the image at the highest quality your pixel dimensions allow, then tops up the remaining bytes with a standards-compliant metadata block — the file lands on 1 MB exactly and the width and height never change.
Will the photo stay sharp at 1 MB?
The picture does not change at all — only the file’s weight moves, so whatever sharpness the original had is exactly what the result has. 1 MB is about data volume, not resolution.
Which forms ask for a minimum of 1 MB?
University application portals, stock-photo desks and scholarship forms — anywhere someone downstream plans to print or enlarge. They assume a lighter photo cannot hold an A4 print.
How do I go from KB to MB on the same file?
Set the target and let the tool do the conversion. A file your computer reports as 240 KB becomes 1 MB when the target is 1024, because the tool counts 1,024 KB to a megabyte, the same as a file browser. Anything above 1 MB is entered in KB, so 2 MB is 2048.
