A SMALLER FILE. ONE LESS OBSTACLE.
Compress an image
to 50KB
Compress an image to 50KB or less without uploading it. Convert JPG, PNG or WebP to JPG on your device. Free for up to 3 images per batch.
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.

How to compress an image to 50KB
- Choose up to 3 JPG, PNG or WebP images.
- This page starts at 50KB. 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.
Fit a 50KB upload field
Use 50KB when a form gives you that ceiling. File size and pixel dimensions are separate limits: a small JPG can still be too wide or too tall. Check the dimensions shown with each result, and keep resizing off if your source already has required dimensions.
Can I compress a signature image to 50KB?
You can select a JPG, PNG or WebP signature image. The output is JPG with a white background, so transparency is removed. Inspect thin strokes at full size before using it. FileSprig does not crop, clean up, or verify signatures, and re-encoding may soften small text.
Will the result be exactly 50KB?
No. 50KB is an upper limit of 50,000 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.
Preparing a photo for a form
Visa, passport, exam and job forms have different rules. Read the guidance for your application, then use its actual size limit.
