MADE FOR REAL-WORLD LIMITS
Compress images for forms and uploads
Some application forms, profile pages, and online services set a strict maximum file size. With Fyloz, choose the limit in KB, prepare a smaller JPEG, and check the result before uploading it elsewhere.
Preparing a photo for an application? Read our step-by-step guide to photo size limits, formats, and upload problems.
Need a 200 KB maximum? Open our image compressor set up for 200 KB.
Still getting an upload error? Read our checklist for why an online form may reject your image.
For strict limits
Try a small target when a form sets a low maximum. Check the preview because strong compression may reduce detail.
For everyday uploads
Start with a moderate limit for photos and documents that need a smaller file without unnecessary size.
Resize instead
If a website asks for exact width and height, use our image resizing tool to set dimensions in pixels.
QUICK ANSWERS
Image compression FAQs
Does my image leave my device?
No. Compression happens locally in your browser; the image is not sent to a Fyloz application server.
Will it always reach my target size?
The tool tries lower image quality and smaller dimensions. Very small targets may be impossible to reach while keeping a usable image.
What format will I download?
The compressed output is JPEG. Transparent areas in PNG or WebP files are filled with white.
Will the image look exactly the same?
Compression can reduce detail, and smaller dimensions reduce resolution. Inspect the preview before using the file.
How do I compress a JPG to 50 KB?
Choose your JPG, set the maximum file size to 50 KB, and select Prepare image. Review the preview and download the result if it looks good.
Can I compress an image to 100 KB for an online form?
Yes. Choose the 100 KB preset, prepare the image, and check the result. If the target cannot be reached for your image, the tool will tell you.
