How to shrink a 20 MB portfolio without losing a pixel you care about

Most image weight is invisible — duplicate metadata, oversized dimensions and a quality setting left at 95. Compressy fixes all three locally, in one pass.

Quality 85Max 2048 × 2048Strip EXIFBackup folder

You don't need to become a codec expert. The default — quality 85 · balanced engine · keep original — is tuned so a typical hero-portfolio.jpg drops from 3.4 MB to 2.5 MB with no visible change at 100%. If you publish to the web, add a max-width of 2048 and you get another 15–30% for free on 4K originals.

What actually saves the most

  • Resizing oversized originals — a 3840×2160 export scaled to 2048 on the long edge removes ~40% of pixels before compression even starts.
  • Re-encoding at 85 — mozjpeg and oxipng are ruthless at this level; 82–88 is the sweet spot for photographs. Below 75 you start to see banding in skies.
  • Stripping metadata — EXIF, ICC and thumbnails add 40–200 KB per file. Keep it only if your workflow needs color profiles.
“The fastest way to make images smaller is to stop shipping pixels nobody will see.”— Compressy default: max 2048, downscale only, keep aspect
◐
Offline means predictable. No upload queue, no per-image API limit. Select a folder of 100 images and Compressy processes them with the threads you allow — 1,000 images in ~5 min on a mid-range Windows PC.
Files stay on disk the entire time. No account, no cloud step.

When to change the defaults

Leave overwrite → backup folder on — originals land in /backup next to each file so you can diff later. Turn lossless on only for PNG line art. Keep skip < 50 KB enabled; tiny icons rarely benefit and compressing them just wastes time.

Quick start — Select, set, compress

Compressy is a single-window Windows utility. Pick a folder, tune four controls, select the files you want and run. Nothing leaves your machine.

  1. Browse to C:\Users\Alex\Pictures\Portfolio — the file list populates with size and dimensions.
  2. Set Quality 85, Engine balanced, Output keep original. Enable More settings only if you need resize or rename.
  3. Select images (checkboxes, or switch to grid) and hit Compress selected →. Results appear inline with −27% · −904 KB per file.
C:\Portfolio> compressy --quality 85 --engine balanced --keep-original
Selected 12 images · 18.4 MB → 13.1 MB  (−29% · −5.3 MB)
Backups → .\backup\  ·  Renamed → {prefix}-{NNNN}.{ext} when enabled
!
Keep backups on. With overwrite → backup folder enabled, originals are copied to /backup before any write. Turn it off only on a copy of your data.

Quality & engine — the two dials that matter

Quality 85 is the default because it sits at the knee of the curve: lower than 75 shows banding, higher than 90 wastes bytes for no visible gain. Engine balanced blends mozjpeg and oxipng; switch to max for portfolio exports where every kilobyte counts, or fast for quick drafts.

Smaller images, same workflow — without the upload

Cloud compressors add an upload, a queue and a download. Compressy removes all three. The comparison below is measured on the same 12-image portfolio (18.4 MB) on a mid-range Windows PC and a 20 Mbps connection.

What to tell your team

If you ship images to the web, the win is not a trick — it is removing pixels and metadata that the browser never needed. The dense list on the left is real output from Compressy at Quality 85. No demo numbers.

  • Keep originals safe: backup folder is on by default.
  • Rename for handoff: {prefix}-{NNNN}.{ext} keeps ordering stable.
  • Skip tiny files: < 50 KB rarely benefits.
