Compress any JPG, PNG, or WebP to 4MB in your browser — no server upload. 4MB is a common file size limit for image uploads on photography platforms, print-on-demand services, and client delivery workflows where you need to reduce an oversized camera export while keeping quality strong enough for print and editorial use.

Platforms and portals that use a 4MB limit

4MB appears as a ceiling on several platforms where image quality matters: some photography competition submission portals, client proofing galleries, print-on-demand platforms (Redbubble, Society6, Printful at certain product sizes), and high-resolution attachment limits on older email systems. It is also a common informal target in creative brief documents — "please provide images under 4MB" is a standard request from art directors and editors who need manageable files that are still large enough for final layout use.

4MB for print preparation

At 4MB, a JPEG photograph can comfortably hold 4000–6000 pixel images at quality 85+, which is well within the range required for A3 print at 300 DPI (3508×4961 pixels, roughly 3–5MB at high JPEG quality). For larger format prints — A2, 60×80 cm — you'll want to stay closer to the original file. For standard print lab orders at A4 and A3, 4MB is a practical and appropriate delivery size.

One important distinction: some print-on-demand services check pixel dimensions as their primary quality gate rather than file size. A 4MB JPEG that is 2000×1500 pixels will fail a "minimum 3000×4500 pixels for a poster" requirement, even though the file is large enough. Check the stated pixel requirements alongside the file size limit.
