Free, browser-based, no upload required
Reduce any image below 500KB entirely in your browser. Useful for email attachments, social media uploads, cloud sharing and CMS image management. This tool compresses to 480KB by default, giving a safe margin below the 500KB ceiling.

JPEG, PNG, WebP, AVIF, HEIC. All processing stays in your browser.
Default target is 480KB. Adjust the target above if your limit differs.
The 500KB limit comes up most often with email attachments, social media uploads and cloud sharing. Unlike strict government portal limits, these are often soft limits where the file either slows delivery or triggers automatic platform compression. Optimising before uploading gives you better control over the final result.
Email attachments
Corporate mail systems, Gmail and Outlook all handle images under 500KB reliably. Pre-compressing avoids messages being held in outbox queues or bouncing due to attachment limits.
Social media profile photos
LinkedIn, Facebook and Twitter apply their own compression to uploaded images. Starting with a file under 500KB that is already optimised produces sharper results than uploading a large image and letting the platform compress it.
Cloud storage sharing links
Dropbox, Google Drive and OneDrive preview links load faster and render more reliably when shared images are under 500KB, particularly on mobile connections.
CMS and blog image uploads
Content management systems like WordPress and Ghost accept images up to several MB, but pages load faster when post images are under 500KB. This directly affects Core Web Vitals and search rankings.
Many email clients and corporate mail systems apply per-attachment or total-message size limits. A 500KB ceiling on individual image attachments is common in corporate environments and older webmail systems. Compressing your image before attaching it ensures delivery without triggering size restrictions.
Compressing under 500KB means the file must be strictly less than 500KB. This tool targets 480KB by default, providing a clear margin. If you need to hit exactly 500KB for a portal that requires a precise size, use the compress to 500KB tool instead.
Yes. For most photographs, compressing to 480KB produces an image that is visually identical to the original. The binary search algorithm always finds the highest quality that fits, so compression is conservative unless the original is extremely large.
Yes. Pre-compressing your photos before uploading to WhatsApp, Facebook, LinkedIn or other platforms reduces the additional compression these platforms apply automatically. Starting with a file under 500KB that is already optimised produces noticeably better results than letting the platform compress a large original.
Yes. The re-encoding process strips EXIF metadata, GPS location, camera model and other embedded data from the output file. This happens automatically because the codec only writes the pixel data back out.
