A new JPG, not your original. Browser re-encoding reduces quality and can change colors. Resizing may reduce dimensions. Transparent areas become white. Camera and location metadata are not copied.

All shortcuts start at 100KB. Check your form’s own size, format, dimensions, and photo rules. A smaller file does not guarantee acceptance.

How to compress an image to 100KB
Choose up to 3 JPG, PNG or WebP images.
This page starts at 100KB. The limit applies to each output image.
Choose Compress. The tool adjusts JPG quality and, when allowed, reduces dimensions if needed.
Check the actual bytes, dimensions and preview, then download each JPG for free.
Check the form before reducing your photo
A 100KB limit says how many bytes a file may contain; it does not specify its width, height, background or composition. Read the form first, then compress a suitable source photo. FileSprig measures the output bytes and displays the resulting dimensions for you to check.
Does a 100KB photo also meet a form’s pixel requirements?
Not automatically. Keep “Allow smaller dimensions” off if you must preserve your source width and height. If compression fails at those dimensions, check whether the form permits a smaller image. This tool does not crop a photo to a required aspect ratio.
Will the result be exactly 100KB?
No. 100KB is an upper limit of 100,000 bytes, not an exact output size. Each successful result is measured after encoding. A failed image has no download button. Very small limits can noticeably reduce detail.
Will this keep the original image quality?
No. This tool re-encodes the image as a new JPG. Quality, color, metadata, and sometimes dimensions change. Transparent pixels are placed on white. Keep your original file; it is never overwritten. An image already below the limit may not get smaller when converted to JPG.
Can I use this for a visa, passport, exam, or job application?
You can use it to meet a file-size limit. Requirements vary by form and issuing authority, including dimensions, background, format, and permitted edits. The shortcuts all default to 100KB and do not represent official requirements. Check the instructions for your application.
Why can’t my image reach the limit?
At original dimensions, even lower JPG quality may be too large. Enable smaller dimensions or choose a higher limit. Animated images, unsupported files, images above 32 MiB or 40 megapixels, and images with a side longer than 16,384 pixels are rejected. Large files may still exceed your device’s memory. Processing stops if one image takes over 45 seconds.
Are my images uploaded?
No. Your images are decoded and re-encoded on your device. Loading the website uses the network. Optional usage analytics runs only with your permission and never includes your images or filenames. See our privacy notice.
Do I need Pro to finish?
No. Process up to 3 images in a batch and download every successful result for free, without an account. You can start another free batch. Pro is planned as a one-time purchase for larger batches of up to 100 images and ZIP downloads; it is not on sale. ZIP Pick remains completely free.
Before using a compressed photo in an application
Compress a passport photo to 100KB
Use this only when your application accepts a 100KB JPG. Check width, height, head position, background and permitted edits first. The tool does not crop, replace backgrounds or validate passport photos. Recheck dimensions and facial detail after compression.
Photo rules differ by visa and issuing authority. Check the format and byte limit for this application and keep your original. If the form specifies minimum pixel dimensions, disable resizing so that meeting the byte limit does not silently make the image too small.
Photo and signature fields may have different size and dimension requirements. Read each field separately. Before submitting, inspect text, thin strokes and facial detail in the result. This tool does not crop, set exact dimensions or clean up signatures.
Use this for an image attachment in a recruitment form. Confirm that it accepts JPG and keep your original CV or certificate; this is not a PDF compressor. If your image contains text, zoom in to check that it remains readable.
