How much quality is lost when compressing to 500KB?

It depends on the original size and content complexity. Pixvise starts at quality 75 and automatically steps down, keeping the highest quality that still fits under 500KB. Photos usually still look great within a 500KB budget.

What if my image cannot reach the target size?

In rare cases (e.g. an extremely high-resolution original with a very strict target), even the lowest quality may exceed 500KB. You will get the smallest possible file with a notice — try lowering the dimensions and compressing again.

Which photo requirements should I follow for the application system?

Requirements (file size, dimensions, background color) vary by region and year. Always follow the latest official announcement of your application system, then use this page to meet the file-size requirement.

Which formats are supported? Can I batch process?

JPG, PNG, WebP, AVIF, GIF, and HEIC (iPhone photos) are supported. Up to 20 images per batch, 25 MB each, with ZIP download when done.

Will my photos be stored?

No. Compression runs in server memory — images are never written to disk or stored, and are deleted right after processing. EXIF metadata is also removed by default to protect your privacy.

About PPT Images

A several-dozen-slide PPT easily exceeds 100MB, and most of that comes from raw images dragged straight in. Projectors and meeting-room screens have limited resolution — once 3-10MB originals are compressed under 500KB, full-screen playback looks virtually the same, while the file drops from 100MB to around 10MB. Sending by email or copying on site is no longer awkward.

This page presets a 500KB target: the server adjusts compression automatically to keep the best quality under 500KB. For even better results, use the Resize tool to bring the longest side down to 1920px before inserting. JPG, PNG, WebP, and HEIC are supported, up to 20 images per batch.

What users say

I process dozens of product images for new listings every day. Now I drag the whole batch in, and it compresses and zips everything automatically — main images drop from 800-900KB to around 100KB. Uploading is so much faster.

The application system required photos under 200KB and I could never hit it by tweaking quality myself. The target-size feature took 200 and nailed 199KB on the first try. Submitted successfully.

I convert all illustrations to WebP and compress them — articles load noticeably faster. Batch processing plus format conversion in one step, no more hopping between apps.
