Many forms, email services, and upload portals have strict file size limits — often 1MB, 2MB, or 5MB. Resizing an image to hit a specific file size target requires balancing pixel dimensions and compression quality. Glopix lets you dial in target file sizes with a combination of resizing and quality adjustment.

Step-by-Step Guide

  1. 1

    Upload Your Image

    Upload the image you need to get under 1MB. Check the current file size shown on the upload screen.

  2. 2

    Set Target Size

    Enter 1000KB (1MB) as your target file size, or use the quality slider combined with resizing to hit the target.

  3. 3

    Download When Under 1MB

    Process and confirm the output file size shown. If still over 1MB, lower the quality slider and reprocess.

Frequently Asked Questions

How do I reduce an image to exactly 1MB? expand_more

Use Glopix Compressor — upload the image, set WebP as the output format, and incrementally lower quality until the output reads under 1000KB. WebP achieves the target with less visible quality loss than JPG.

Can I reduce a 10MB photo to 1MB? expand_more

Yes — a 10MB DSLR raw photo can typically be reduced to under 1MB by converting to WebP at quality 80 and resizing to 2000px width. Use /imagetools/compress/ for this.

What causes blurry images after compression? expand_more

Setting quality too low (below 70 for JPG, below 65 for WebP) causes visible compression artefacts — blocky patterns and soft edges. Stay above quality 75 for acceptable visual results.
