Why FileReadyNow
Compress Images to a Fraction of Their Size Without Visible Quality Loss
Reduce JPG, PNG, and WebP file sizes in seconds so pages load faster and files are easier to share.
Up to 90 Percent Reduction
Compresses images aggressively while keeping the visual result clean and sharp for web, email, and social use.
Adjustable Quality Level
Dial in the compression level yourself to decide how much to shrink the file versus how much detail to keep.
Batch Compression
Upload multiple images at once and compress them all in a single operation rather than one at a time.
Before and After Size Report
Shows original size, compressed size, and percentage saved for each file so you can see exactly how much you gained.
Deleted Automatically
Your images are compressed on our server over an HTTPS connection, and both the uploads and the results are deleted automatically within about an hour.
No Account Required
Upload your images and download the compressed versions. No signup, no watermark, and no file count limits.
Image files accumulate fast and get large quickly. A single unoptimized PNG from a design export can be 5 MB or more. Multiply that across a page with a dozen images and your load time takes the hit. This compressor reduces JPG, PNG, and GIF file sizes in seconds. Uploads are deleted as soon as they are processed and compressed files are removed from our servers within an hour.
How image compression works
Each image is re-encoded at its original resolution with modern encoders. PNGs are reduced to an optimized colour palette and then losslessly recompressed. JPG, WebP and AVIF quality is tuned per image so the file is as small as possible without visible change. Metadata such as camera EXIF data is removed for privacy. The compression percentage shows up on each file so you can see exactly how much was saved before downloading.
What formats are supported
The compressor accepts all common image formats:
- PNG: Lossless originals get re-encoded to a smaller output. Good for graphics, screenshots, and images with transparency.
- GIF: Animation is kept. Convert to WebP for a much smaller animated file.
- WebP, AVIF, HEIC and TIFF: Compress them, or convert to JPG, PNG, WebP or AVIF. iPhone HEIC photos are saved as JPG unless you pick another format.
- JPG/JPEG: Photos and realistic images compress particularly well. The visual difference at this quality level is not noticeable to the eye.
When people use this
- Website performance: Page weight is one of the most direct things you can reduce to improve load times. Compressed images make a measurable difference on image-heavy pages.
- Email attachments: Most email providers cap attachment size. Compressing images before attaching them prevents bounces and delivery failures.
- Social media uploads: Platforms recompress on upload anyway. Sending a pre-compressed image gives you more control over what the final result looks like.
- CMS and blog uploads: WordPress and similar platforms store every uploaded version of an image. Uploading smaller originals keeps your media library manageable.
- Storage and archiving: Compressing a folder of product or event photos before archiving can cut storage use significantly with no visible quality difference.
How much quality you actually lose
For most images the answer is: not enough to notice. Photos and detailed images with gradients compress well at this quality level with no perceptible difference when viewed normally. Flat color graphics with sharp edges may show subtle softening under close inspection, which is normal for any lossy compression. The output is ready to use for web publishing, email, and most print uses without further adjustment.
