Direct answer: Keep the original image as a master, export one JPEG copy for a photo listing, and inspect it at 100% for fine texture, lettering, and edges. Do not convert to WebP by default or compress merely to force every file below 1MB. If an upload does not finish, reduce quality in a new copy while holding the dimensions constant. Treat upload failures and thumbnail crop softness as separate problems.
Understand the three variables
Etsy’s current documentation lists JPG, GIF, PNG, SVG and HEIC for listing images; WebP is not listed. Files over 1MB may fail to finish uploading, especially on slow connections, although 1MB is not a universal hard limit. Etsy advises using sRGB when colors appear wrong and applies its own compression after upload. Transparent PNG areas can also appear black.
Those details do not make file size the only consideration. Dimensions describe the image’s width and height. File size describes how many encoded bytes the file contains. Detail describes the visible information in the picture, including texture, sharp edges and small lettering.
Reducing dimensions removes pixels. Recompressing an already compressed image can soften details or introduce visible artifacts. A file can therefore have modest byte size but poor visible quality, or remain highly detailed while using more bytes. Decide what must remain visible before deciding how much to compress.
Use a one-copy photo workflow
- Preserve the master. Keep the original file unchanged in a separate folder. Do not repeatedly save over it with a lossy format, because each additional JPEG save can reduce the available quality.
- Create one upload candidate. Duplicate the master and export that copy as a JPEG. This gives you a practical photo file to inspect and upload without risking the source.
- Check the intended dimensions. Compare the working copy with Etsy’s current listing-image size recommendations. Do not adopt one pixel width as a universal target for every product, camera or design.
- Inspect before uploading. View the candidate at 100% and look closely at fabric, fur, hair, reflective surfaces, fine patterns and text. Also check the edges for halos or abrupt smoothing.
- Change one thing at a time. If the upload fails, create another copy at lower JPEG quality while leaving its dimensions unchanged. That makes it possible to tell whether the change helped.
Choose the format by the asset
| Starting asset | Practical export choice | Reason |
|---|---|---|
| Photograph | Single JPEG copy | Simple to review and suitable for testing subtle compression artifacts. |
| Graphic with transparent areas | Composite onto the intended opaque background for the listing copy | Do not rely on transparent PNG areas staying transparent on Etsy. |
| Flat vector artwork | Keep the vector master; create an inspected listing derivative | The editable source and the buyer-facing preview have different roles. |
| Animated source | Choose a truthful still image for the listing photo | Etsy does not support animated GIF listing images. |
| WebP source | Export an inspected JPEG or opaque PNG copy | Do not assume support for a format absent from Etsy's list. HEIC, in contrast, is listed. |
Record exports before testing them
The following is a planning worksheet, not a record of measured results. Keep one upload candidate at a time and document each export before deciding whether another adjustment is necessary.
| Filename | Source | Size | Result |
|---|---|---|---|
| master-original.* | Original source | Record original pixel dimensions and bytes | Preserved; not uploaded |
| etsy-photo.jpg | master-original.* | Record exported pixel dimensions and bytes | Texture, text and edges inspected |
| etsy-photo-adjusted.jpg | master-original.* | Record the new export dimensions and bytes | Same dimensions; lower quality only if needed |
If the problem is framing rather than upload weight, make a new crop from the master instead of compressing an already incorrect crop. Keep filenames distinct so the final upload is not confused with an experimental version.
Diagnose the actual symptom
If the upload does not finish
Focus on transfer weight and connection reliability. Check the current file’s byte size, then test a lower-quality copy with identical dimensions. Do not resize, crop and recompress in one step, because then you will not know which change affected the outcome. A successful upload resolves only the completion problem; it does not prove that every visible detail survived intact.
If the thumbnail crop looks soft
A completed upload can still produce a thumbnail that looks softer than expected. Review the crop itself, including how much the selected area is enlarged. Use the related thumbnail-crop article to check that workflow. Do not reduce JPEG quality automatically: if the full-size candidate is crisp but the crop is soft, changing compression may conceal the real issue rather than fix it.
Use this final pre-upload check
- Keep the untouched master available.
- Export one JPEG candidate for each photograph.
- Inspect texture, lettering and edges before upload.
- Follow Etsy’s current size recommendations without turning one dimension into a rigid rule.
- Lower quality only after an upload problem occurs, and change one variable per test.
- Address crop softness separately from file-weight failures.
