Compress any image to 250KB or less automatically. For blog photos, email graphics and CMS uploads where high quality is needed within a 250KB limit.
Drop your JPEG or PNG. At 250KB, large web photos up to 1200×900 pixels compress with excellent quality. Original size and dimensions shown.
Binary search finds the highest JPEG quality at or under 250KB. Most large web photos achieve quality 80–90 at this budget — visually excellent.
Review before/after quality and download your 250KB image.
250KB is a reasonable size for medium-to-large website images. A 1200×800 pixel blog hero image at 250KB achieves JPEG quality 75–82, which is excellent for web display. Google PageSpeed recommends optimising images — if your current images are 1–3MB, compressing to 250KB achieves 75–90% size reduction while maintaining visual quality.
250KB allows approximately 25% more data than 200KB, resulting in a higher JPEG quality setting for the same image. For a 1200×800 pixel image, 250KB achieves roughly quality 75–82 versus quality 70–76 at 200KB. The visual difference is subtle but measurable for large images with fine detail.
Facebook and Instagram accept images up to 30MB, so 250KB is well within their limits. However, these platforms re-compress images anyway, so the original quality before their compression matters less than at other destinations. For social media, focus on getting dimensions right (1080×1080 for Instagram square posts) and use 250KB for a good balance of upload speed and source quality before platform re-compression.
No — pixel dimensions are preserved exactly. Only JPEG quality is adjusted to hit the 250KB file size target. If your system requires specific dimensions alongside the file size limit, resize your image to those dimensions first, then compress here.
Yes — 250KB is a practical size for blog images. Both WordPress and Ghost apply their own compression on upload, so a 250KB source will result in an even smaller stored file. For featured images displayed at 1200px wide, 250KB provides excellent quality. For smaller in-post images, 100–150KB is more appropriate to keep page loads fast.
