A single high-resolution printable can blow past Etsy's 20MB-per-file limit without you doing anything unusual — a 24x36in poster at 300 DPI is 7200x10800 pixels, and as a PNG that's often 25-40MB before you've touched anything else. The fix isn't lowering your resolution and hoping nobody notices the print quality drop. It's compressing the file properly, which can cut it by 60-80% with no visible difference on screen or in print.
Etsy rejects any single digital file over 20MB, and high-resolution printables are the most common file type to hit that wall. Proper compression — not just lowering the resolution — usually gets a print-ready file well under the limit while keeping it sharp enough to print cleanly. Scaylr's free Image Compressor handles both PNG (palette reduction, keeps transparency) and JPEG (quality-based compression) in your browser, up to 60 images at once, with no upload to a server.
Why is your file over 20MB in the first place?
File size scales with pixel count and color complexity, not with how the design "feels" in terms of detail. A large, high-DPI printable has a lot of pixels by design — that's what makes it print sharp at 24x36in instead of pixelating. The problem isn't the resolution itself; it's that an uncompressed or lightly-compressed export of that many pixels is naturally large, and Etsy's limit doesn't scale with product size.
| File type | Typical cause of large size | Best fix |
|---|---|---|
| PNG | Millions of unique colors, or a photo-like gradient | Palette reduction (down to 256 colors) — invisible on flat-color designs, minor tradeoff on photo-heavy ones |
| JPEG | High quality setting on a large image | Quality-based compression — drop from 100% to 85-90% is usually invisible |
| PDF (multi-page) | Uncompressed images embedded per page | Compress each image before placing it in the PDF, not after |
Lowering DPI to shrink a file is the wrong lever — it directly reduces print quality. Compression is the right lever because it removes redundant data (repeated colors, unnecessary color precision) without changing the pixel dimensions your buyer prints at.
How do you compress without losing print quality?
Upload your file (or up to 60 at once)
The Image Compressor runs entirely in your browser — nothing is sent to a server, which also means no wait for an upload/download round trip on a large file. It handles a batch of up to 60 images in one pass, useful if you're prepping an entire multi-size bundle at once rather than one file at a time.
Choose PNG or JPEG compression
For PNG, the tool reduces the color palette (up to 256 colors) while keeping transparency intact — the right choice for flat-color designs, line art, and most printables, where the image doesn't rely on millions of subtle gradient colors. For JPEG, it uses quality-based compression, which works well on photo-style or gradient-heavy designs where PNG's palette limit would show visible banding.
Check the before/after size, then export
Compare the compressed size against Etsy's 20MB cap before downloading. Most single-page printables drop well under the limit on the first pass; a dense multi-layer design with lots of texture might need a second look at quality settings.
If a file is still over 20MB after compression — usually only an issue with very large multi-page bundles — the other option is splitting the deliverable across Etsy's 5-file limit (covered in a separate guide on that limit specifically) or using a linked PDF with the real files hosted externally.
PNG vs JPEG for a printable: which should you compress?
| PNG (compressed) | JPEG (compressed) | |
|---|---|---|
| Best for | Flat colors, line art, text-heavy designs, transparency needed | Photo-style art, gradients, textured backgrounds |
| Transparency | Preserved | Not supported (always has a background) |
| Compression artifacts | Palette reduction is lossy too: gradients can show banding, flat colors usually look unchanged | Minor, usually invisible at 85%+ quality |
| File size on gradients | Can stay large even compressed | Compresses much further |
If you're not sure which applies to your design, err toward PNG for anything with flat backgrounds and crisp edges (most Etsy printables), and JPEG for anything closer to a photograph or heavily textured background.
A quick pre-upload checklist
- Compress every size variant in your bundle, not just the largest one — a "small" 5x7in file can still be surprisingly large if it was exported at the same DPI as the 24x36in version.
- Check the compressed file still looks correct at 100% zoom before uploading — palette reduction on a design with more than 256 distinct colors can occasionally introduce visible banding, worth a quick eyeball check.
- Keep an uncompressed master copy saved separately in case you need to re-export at a different size later.
