Online application forms
Prepare signatures, headshots or scanned supporting images for a fixed 100KB rule.
Private, browser-based image resizing
Increase image size to exactly 100KB
The exact 100KB preset targets 102,400 bytes, which is useful when an upload field rejects files that are smaller or larger than the stated requirement.

Your images do not leave this tab
Processing and downloads happen locally. Refreshing or closing the page clears the current queue.
Set your target and add images
1 KB = 1024 bytes. 1 MB = 1024 x 1024 bytes.

Drop images here or choose files
JPG, PNG or WebP. Up to 20 files, 20 MB each.
Image queue
No images selected yet.Choose one image or a batch of up to 20 files.
When a 100KB target is useful
Choose Exactly when the portal states 100KB as a fixed value. Choose At most when it says 100KB or less. The result panel shows the actual bytes, output format and any dimension change.
Recruitment portals
Match a required byte count before adding an image to a job profile.
Three steps, no upload
The controls are intentionally direct. Choose images, set the byte requirement, then download verified results.
Select
Add one JPG, PNG or WebP, or choose a batch of up to 20.
Set target
Choose exact, maximum or minimum size in KB or MB.
Download
Every result is decoded and checked again before download.
Why exact KB matters
Government forms, job portals, exams, identity documents and content systems often enforce rigid file limits. A valid image can still be rejected when its byte count falls outside the stated range. This tool changes the encoded file size without claiming to create new visual detail.
File size and dimensions comparison
KBstored bytes
PXwidth x height
File size is not image dimensions
KB and MB measure stored bytes. Width and height measure pixels. An image can keep the same dimensions while its encoding changes, but a very small maximum may require dimension reduction. The result always reports both values.
Choose the format that fits the job
JPG
Usually compact for photos. Transparency is replaced with white.
PhotosPNG
Keeps transparency and sharp edges, but can be larger for photos.
TransparencyWebP
Often provides a useful balance of size, quality and transparency.
Modern webLocal processing is the privacy feature
The site does not need your image data to resize it. Files, names, previews and output blobs remain in browser memory. Optional analytics can record anonymous actions such as a completed batch, never file contents or file names.
Questions about exact image size
What does exact mean?
The downloaded Blob must contain exactly the target number of bytes. Targets use 1KB = 1024 bytes and are verified after processing.
When should I use At most?
Use it for an upload ceiling such as 100KB or less. The tool does not add filler to a result that already satisfies the limit.
Are my images uploaded?
No. Processing happens in the current browser tab. The server does not receive image contents, file names or output files.
Is metadata kept?
No by default. Re-encoding removes common EXIF metadata, which can include camera and location information.
